Hi, thanks for reporting.

Could you please upload the /etc/fstab and /var/log/syslog file from the Live system?

/etc/fstab and /var/log/syslog persistent mode boot Edit (29.2 KiB, text/plain)

Here's /etc/fstab and /var/log/syslog from just after CD Live persistent boot with 20070213. Let me know if the attachment doesn't come over O.K.

I usually test with this Celeron system which is quad boot with Dapper, Edgy, Xubuntu, and Win98. I do have a laptop and three other Intel systems with various video adapters, monitors, and processors if the type of hardware would make a difference. I usually try them with persistent because Herd 2 fdisk to the USB pen drive trashed the Celeron's hard disk partition table.

I've booted 20070213 several times today; once the desktop showed two casper-rw icons with the same UUID. Since the boot was persistent it shouldn't have showed any casper-rw icon.

With persistent I can install Flashplayer, Real Player, ndiswrapper wireless, do many internet videos (not ActiveX), ...

When shutting down Herd's 4 and 5, the following error message shows up:

* Unmounting temporary file systems. . .
umount: /cow not mounted
[fail]

I am new to Linux, so don't know if this is relevant, but I didn't see this error message with Herd 3 in which persistence seems to work and it looked like /cow may be used by casper.

I'm also facing this same problem. Is there anything I can do to debug this?

It seems that this problem needs to be fixes asap as the final release is not far away. I would also like to suggest to upgrade the importance of this bug.

Screenshot of USB key icon appearing on Desktop Edit (313.3 KiB, image/png)

Experiencing same problem with the Kubuntu Feisty Fawn Beta CD iso (Version 7.04, built on 20070322.1)

Symptoms:
- No persistence was observed (bookmarks, software installed from Adept)
- Creating a new user (other than the default, 'ubuntu') did not help.
- The casper-rw icon for my USB key appears on the desktop.
- An error about "unable to umount /cow" appears on shutdown
- Casper claims to be syncing files at shutdown, but nothing is written to the USB key.

Hopefully this can be fixed before Feisty goes prime time!

The casper-rw icon shows up on the desktop. Nothing is written to the USB stick during a "persistent" session. No persistency is achieved.

I can provide more info and do some tests, just let me know what you need.

In comparing the Herd3 casper.log to the Beta casper.log on my system, I noted the following difference. In reviewing the following scripts, note that I am booting the LiveCD off of a USB device that contains the LiveCD files in the manner described in one of the Ubuntu Wiki's. Hence the references to sdb1 below. I follow exactly the same approach for Herd3 and Beta, but persistence works for Herd3 and not the Beta distribution.

The casper.log from the Beta distribution reads as follows.

Begin: Running /scripts/casper-premount ...
Done.
Done.
mount: Mounting /dev/sda1 on /cdrom failed: No such device
mount: Mounting /dev/sda1 on /cdrom failed: No such device
mount: Mounting /dev/sda1 on /cdrom failed: No such device
mount: Mounting /dev/sda1 on /cdrom failed: No such device
mount: Mounting /dev/sda1 on /cdrom failed: No such device
Done.

All of the "No such device" failures are missing in the Herd3 casper.log. Again, don't know if this is relevant and I am a newbie, but it appears that this failure is occurring while running the scripts in the casper-premount directory. Looking in that directory in the Beta distribution, there is only the 10driver_updates script. I have repeated part of that script below.

#!/bin/sh

PREREQ=""
. /scripts/casper-functions
. /scripts/casper-helpers

[I HAVE OMITTED A PORTION OF THE SCRIPT HERE]

mountpoint=/cdrom

[I HAVE OMITTED ANOTHER PORTION OF THE SCRIPT HERE.]

check_dev_updates ()
{
    sysdev="${1}"
    devname="${2}"
    if [ -z "${devname}" ]; then
        devname=$(sys2dev "${sysdev}")
    fi

    fstype=$(get_fstype "${devname}")
    if is_supported_fs ${fstype}; then
        mount -t ${fstype} -o ro "${devname}" $mountpoint || continue
        if is_updates_path $mountpoint; then
            return 0
        else
            umount $mountpoint
        fi
    fi

return 1
}

[I HAVE OMITTED THE REST OF THE SCRIPT.]

I did not see this script in Herd3 at all. As best as I can tell, the "mount" command shown above is where the mount failure is occurring, although I again am still in the process of learning Bash and Linux so I don't really know enough to evaluate this further at this point. While this script appears to be looking for driver updates, it is mounting the /cdrom directory. I wasn't sure if the failure in mounting the /cdrom directory might affect persistence in another script. Even if it doesn't, it does appear that one of the variables used in this mount loop is wrong and that causes me to wonder whether that error may have bearing on the persistence failure. In particular, on my system, the LiveCD cdrom files are located on sdb1 and not on sda1. So, I assume sdb1 should be mounted at /cdrom, not sda1 as it looks like this script is trying to do. On my system, my internal hard drive shows up as sda1. I am not sure why that is the case. It is my work laptop and I think it is an internal IDE drive. But it is that way on both Herd3 and the Beta distribution, and this error does not appear when booting the Herd3 distribution. It is an NTFS formatted drive which is probably why it is not available during boot. I haven't updated my fstab to mount it. Even if I did, it...

I've come up with a temporary solution that meets at least my needs (until someone actually fixes the packages).  I have generated a Feisty LiveUSB disk that for the most part includes the packages from the final version of Feisty, but I have specified that certain packages are to remain at the Herd3 level, allowing persistence to still work.

Basically, I used a "Preferences" file (I have attached the one that I used) in the manner I describe below.  This Preferences file prevents the files that it lists from upgrading when I upgraded the Herd3 files to the final version of Feisty.

I used this Preferences file to generate a new version of the following files on my Live disk:

/casper/filesystem.squashfs
/casper/filesystem.manifest
/casper/filesystem.manifest-desktop
/md5sum.txt

I generated these new files, again, following essentially the approach at this link:  http://www.atworkonline.it/~bibe/ubuntu/custom-livecd.htm

My comments below refer to the procedure outlined at that link.

I generated the ubuntu-fs.ext2 file, containing the ext2 filesystem, as described.  I actually used a 4GB file instead of the 2GB file shown at the link because I ran out of space, when upgrading, using the 2GB file.  (I believe that the larger file does not ultimately cause you to consume additional space on your usb disk because of the effect of creating and deleting the "zeroed" dummyfile).  I mounted this ext2 filesystem and copied the "unsquashed" filesystem from the Herd3 iso into that directory (i.e. unsquash into this directory the contents of the /casper/filesystem.squashfs file from the Herd3 iso).

Either prior to or after chrooting into this file system, I copied the attached Preferences file into the /etc/apt directory of the unsquashed filesystem.  Again, this will "pin" the listed files at the Herd3 versions listed in the attached Preferences file.  See the Apt How-To for a more detailed description of "pinning."  (I haven't tried to upgrade from Edgy.  But if you are doing that, then I suspect you at least need to change the file names and versions in the attached Preferences file to the corresponding Edgy files).  In my /etc/apt directory, I also updated the sources.list file to be sure it had the repositories I wanted.  There is a Wiki guide (I believe it is called a Feisty Startup Guide) that lists available repositories.

I mounted and chroot'ed into this filesystem, exactly as shown at the link above.

I executed "apt-get update" to update the list of files available at the repositories.  I then used aptitude to run both the upgrade and dist-upgrade commands in that order.

aptitude upgrade
aptitude dist-upgrade.

I ran these commands again (I might have used apt-get, instead of aptitude, the subsequent time(s), although it shouldn't matter) until I got feedback that there were no additional files to be upgraded or added.  Note, I did get feedback that the "libdevmapper1.02" package was broken (this is one of the "pinned" packages).  But, I ignored that because I selected that as one of the files to not be upgraded.  The result still worked for me.  I don't know if others will experience the following issue, but I also had to work through an issue of not being able to upgrade certain packages associated with acpid.  There are links related to that issue.  But, I worked out all apparent issues before re-squashing the filesystem.

After finishing the updates and upgrades, I made some additional changes (e.g. added ntfs-3g and bootchart) that I expect do not affect the persistence issue; exited out of the chrooted environment, generated the new filesystem.manifest file (I used this exact same file as the updated filesystem.manifest-desktop file); resquashed the filesystem; generated the new md5sum.txt file; copied the resulting files to my usb drive per the instructions for generating a live usb, and rebooted.

The boot was pretty slow (I may need to try some of the approaches for speeding up boot time), but it does boot fine and the basic persistence works fine.  While I haven't tested the result extensively, visually it looks (and at least initially seems to operate) like the final version of Feisty.  I am attaching a copy of the filesystem.manifest in case anyone wants to see the differences between the packages I used and those used in the final version of Feisty.  I can also upload the re-squashed filesystem(assuming that that is not inappropriate for some reason), but I haven't done that because I expect people may want to generate their own version of the custom squashed filesystem.

It seems possible that my result could be duplicated with less effort.  E.g. start with a LiveUSB drive that uses the Herd3 version of Feisty, and simply copy the attached Preferences file into the /etc/apt directory of the booted LiveUSB, and then upgrade that booted LiveUSB in the same manner as you normally would.  But I expect that that approach will take a lot more room on your casper-rw partition because the upgraded files will go onto the casper-rw partition, instead of being part of the CDRom image.  I haven't tried that approach, so don't know if it will work.

I honestly do not know if all of the files that I have "pinned" need to be pinned, although I think at least most of them probably do (e.g. I don't know if upstart-logd needs to be pinned, for example).  But, for my purposes, I don't really care.  It would be interesting to see if Colin Watson's changes above, combined with pinning a subset of the files I have pinned, though, can be made to work.  I am not going to have time to do that, but it might help narrow down the cause of the issue.

Great news! Mike, maybe we could get this hybrid Herd3/5 LiveCD circulating as a torrent?

I've never done that before, but it's not rocket science. We just need you to seed it (recent versions of Azureus have a built-in tracker) and send us the torrent. I'll gladly keep it seeding from my Linux box.

For security reasons, it will be important to clearly identify your disk image as an unofficial Ubuntu release that is your own creation and include an MD5 sum in the description. This way users will not confuse your disk image with official Ubuntu releases and can 'trust' the contents of the image as your own by verifying the MD5 sum.

I think that's the best way for you to share your effort with the community. Email me directly if you want help organizing it.

That sounds good, Fisselfink. I actually may not be able to get this going until some time next week. My wife has been giving me some dirty looks for the time I have spent. But, there are a couple things I still want to check out.

I suppose it probably makes sense to make all of the files available in the form of an iso, just like a ubuntu distribution (unless someone has other thoughts), and probably makes sense to make it available without my other "customizations" (e.g. not add ntfs-3g, bootchart, etc.). That way, it is a "base" image, similar to the ubuntu distrib.

Also, I am experiencing a problem installing the Java JRE and plugin. It does not look like it is a problem unique to this hybrid. But rather, appears to be a problem that others have experienced (e.g. I think it is failing to configure Java, saying it cannot locate libjli.so and libjava.so - or something to that effect - I don't have the error messages in front of me now). Although I believe Java is not in the base distribution, it would be nice if I could resolve that before making this available. But I don't think I am going to have time to figure it out. I expect it is probably an issue that can be fixed by making changes in persistent mode, but again I haven't worked it out.

I guess, people should assume there may be issues and test it out and provide feedback. It may need more fine tuning. I am also am wondering whether it would make more sense to start with Edgy and upgrade from that (so that the Edgy version of the relevant files are pinned, rather than the Herd3 versions). Again, I may not have a chance to figure that out soon. If anyone wants a copy of this earlier than next week, I don't mind making it available in exactly the form I have it now, as long as everyone recognizes that it may still be a little "rough."

Vincent,

I found a Ubuntu link to the Herd3 iso, but it wasn't working. Does anyone know if the Herd3 is stil being made available? If not, I guess that that may be another reason to start from Edgy.

Mike (mike0999) wrote on 2007-05-18:

#33

One other interesting point. I didn't make this clear in my earlier posts, but it looks like you may need to use the new manifests and squashed filesystem with the files from the herd3 iso (rather than with the files from Feisty final iso) to get it to work. I tried using the exact same manifests and squashed filesystem with the files from the Feisty final iso and persistence didn't work. But, when I copied the exact same files into the files from the herd3 iso, it worked.

Not sure why that would be the case, and I haven't had a chance to double check to make sure I didn't do something else wrong. But, just an fyi for anyone trying this. You might try it both ways as well to see what results you get.

I've been playing with the Xubuntu 7.04 CD and a 4GB flash stick. I suspect this bug is a 7.04 kernel/module problem. Quite simply, persistence is borked because unionfs isn't loading. (Just type "mount" and you'll see "unionfs on / type (rw)" is missing and you can confirm it with "lsmod | grep unionfs" too.) As a hack, I copied vmlinuz and initrd.gz from a 6.10 CD to /usb and /usb/casper (I guess it must be copied to both places because links don't work in vfat) and persistence worked. Unfortunately, other stuff seems to break with the 6.10 kernel--the LAN is dead on at least one of my live USB hosts and the PS2 mouse is dead on another host. USB keyboard and mouse seem to work. At one point, I couldn't mount the ext3 filesystem on my hard disk, but that problem seems to be mysteriously absent now.

Next I attempted to build unionfs into the kernel, rather than a module, but the build ended with an extended attribute (xattr) conflict with other filesystem modules. At this point, I really don't know how to build a kernel for a live CD anyway. If anyone can point me in the direction of a howto, we may be able to solve this.

Cal, that's interesting. The problem was not present in Feisty Herd 3. If someone could copy vmlinuz and initrd.gz from a Herd 3 CD to /usb and /usb/casper , it may cure the problem with less side-effects than you experienced. I might even be a viable workaround altogether. It's really annoying that there seems to be no way of getting my hands on a Herd 3 image.

KennoVO (kenno-xs4all) wrote on 2007-05-20:

#37

Looks like I've been a bit too optimistic. I found a Herd 3 image and applied the same procedure as described by Cal. The good news is that persistence works, and that the logs written onto casper-rw indicate that most of the hardware is correctly recognized and initialized. The bad new is that I've also seen some ugly error messages passing by, and that I don't get any login prompts in the virtual terminals. Which is really bad because X fails to start as well (that happens with all Ubuntu live CDs on my laptop). Sure, I could make a customized xorg.conf file on the casper-rw filesystem and see what happens, but as copying the vmlinuz and initrd.gz files is just a dirty hack, it may not merit further effort. Besides, I'm too tired to continue. Moreover, I discovered that my casper-rw partition is too small to make persistence really useful (gconf immediately fills it). Hope you guys can work out a cleaner solution for the persitence problem, though. I'm sure it would make a lot of people very happy.

Okay--now I'm getting somewhere. I think the problem is 7.04 is using an incompatible version of Unionfs. I don't have much time to work on this so maybe we can regroup in the forums--and it's probably best not to clutter this bug report while we work on a fix. Please see my posting for more info:

I haven't figured that out completely myself. But, I typed "persistent" at
the "boot " prompt and hit return and it booted into persistent. You might
try that, but I'll see if I can look at it more closely.

Vincent,

When booted into the system from which you are issuing the "syslinux" command to create your persistent drive, make sure you are using the gutsy versions of syslinux and mtools (mtools may not have changed from edgy and feisty). That fixed the problem for me completely. If that system isn't gutsy, and you don't want to upgrade the entire system to gutsy, you can still upgrade only those two packages by changing your sources.list temporarily to gutsy, and then issuing sudo apt-get update, and then sudo aptitude install syslinux, for example.

So, all I did was boot up on a drive other than the one I wanted to make persistent. I took a usb drive on which I had been using the patched feisty system (so prepared exactly in accordance with your tutorial). I then deleted everything from the partition containing the cd-rom files except for syslinux.cfg (i.e. I am using exactly the same syslinux file as for the patched feisty system). I then copied all of the gutsy beta files onto that partition, except for the isoconfig (or whatever the syslinux.cfg file was called before we renamed it to syslinux.cfg). I also deleted everything off of the casper-rw partition other than the lost and found directory (and my home directory). I then issued the syslinux command (again with the gutsy version of syslinux installed), and I am good to go.

Note, if this works for you, I did experience a large number of freeze ups with firefox, which I believe is a reported firefox issue. I currently have the "fasterfox" add-on installed because some people said that fixed the problem for them. So far I haven't re-experienced the firefox freezes, but I need more time to assess whether or not that really fixed the issue.

I also downgraded to the edgy versions of the 3 upstart files as I described above. That fixes a failure to unmount local filesystems that I have been experiencing since the feisty upstart upgrades. You will probably run fine if you don't do that downgrade, but if you receive the failure to unmount local filesystems error on shutdown, you probably will need to do that downgrade to avoid causing errors on your persistent drive.

Sorry, when I said "all of the gutsy beta files" above, I meant all of the appropriate gutsy beta files, again per your feisty tutorial.

So, everything is per your original feisty tutorial, except you need to be sure you issue the syslinux command with the gutsy version of syslinux installed.

First of all: I'm writing this from my persistent USB, which worked after I typed "persistent" at the boot prompt, as you wrote.

I did realize I had forgotten to clear my casper-rw partition, so the theme looks a little bit odd and during boot up Xubuntu wanted to start MySQL which wasn't installed...

Anyway, it's great that you found a way to fix the problem. When I've booted into the normal system again I'll try using a newer version of syslinux.

Also, I found that the pendrivelinux tutorial was a bit unclear unless you already knew how to make it persistent. Is there anyone who could use a more extensive tutorial? If there is, please add a comment here then I'll write one.

Great work again Mike :)

I'd love to see a complete step-by-step tutorial for this, covering how to
create a bootable USB drive and how to make it persistent. Most of the
instructions for formatting the drive etc. are over at
http://www.pendrivelinux.com/ so I'm sure these can be used as a starting
point.

jhonan, I've already posted a previous tutorial on Ubuntu Feisty, and I've done it so often by now anyway so I could probably do it by heard ;-)

I'll probably just write a normal tutorial on putting Ubuntu or any of its derivatives on a USB drive, and get the reader to download the edited initrd.gz.

I am not sure you need to edit the initrd.gz (at least I didn't have to). I
really think persistence may be completely fixed in the beta iso; at least
it is working for me without any mods.

Really? Great news! I'll go and replace my initrd.gz with the original, then, and just write a single definitive tutorial on putting any *buntu on USB :)

Im not sure how I missed this but,
7.10 Beta - 9/27/2007 ?
I figured it would have been renamed, but I guess it only changes with
official releases.

So, does this build work with persistence for sure? Anyone tried

wilsonb, Xubuntu Gutsy beta works for sure without any special modifications other than the normal steps required to make it persistence. The step using syslinux does need to be Gutsy's version of syslinux though (or you would end up at a boot prompt every time where you would have to type "persistent" to boot into persistent mode).

wilsonb, PendriveLinux has one [1] but I haven't tested it and it seems that it makes you download some U710fix.tar which isn't required anymore.

Furthermore, as far as I'm aware, there currently is no such guide (though I will be writing one soon, I hope). However, my guide on Ubuntu Feisty [2] should work too, albeit that instead of the ISO named there you'd need the Ubuntu Gutsy ISO (and at a certain point it asks you to copy the dists folder or something, which doesn't exist but that doesn't matter), and where it asks you to do sudo syslinux -f /dev/sdx1 you'd best do it from a Gutsy liveCD or something, as you need that version. Hope that helped, and if you have any questions you can just ask :)

Persistent mode doesn't work for me in gutsy. Followed the direction on the ubuntu wiki, and was able to get the USB drive to boot properly (actually writing this from a liveUSB right now), but Persistent mode does not save settings properly.

I believe that I'll have to edit up the init file in order for this to work properly, but I'll post back with my findings.

Clarification on the above.

Looks like I was able to get a bit further after reformatting my casper-rw partition.

Getting some odd KDE errors where its having problems reading/writing from certain files.

Originally it was /home/ubuntu/.kde/share/config/kdeglobals

Now it seems to be /home/ubuntu/.ICEauthority

It seems that for some odd reason, persistent mode is creating files with a chmod of 000. Whenever I try to change the permissions on these files, I get Input/Output errors.

Not sure what's happening here.

waxhell: If I'm using persistent mode (home or root type) with the iso contents as well as the persistent fs on a USB key, I get block devices errors on the USB key on shutdown, the persistent fs isn't unmounted cleanly, and sometimes some files seem to get corrupted, particularly files that are likely to be open continuously during the session (e.g. ICEauthority) or immediately prior to shutdown (settings files.)

Booting from a CDROM (and still using the USB key for the persistent fs) seems to work OK (at least for home mode - root mode doesn't wait long enough for the USB key to settle before deciding there's no persistent fs to union mount.)

I need to look into the shutdown scripts more closely, I think.

On Hardy I cannot achieve persistence, I follow the tutorial on wiki (LiveUSBPenDrivePersistent) and the Ubuntu starts but finish on a initramfs and as I a novice I have to reboot. AFAIK and reading this looong conversation looks like as someone else downgrade something and the persistent on USB thumb or HD fails in the final release after this guys fixed the persistent problem.

The problem is still there, because on www.pendrivelinux.com for ubuntu gutsy only convert the USB on Live Ubuntu but without persistence, and in some other forums and articles everybody ask about persistence unsuccessfully or we need to edit some files as <a href="http://www.ryancloke.com/ubuntu-804-hardy-heron-live-usb-how-to/"> this link shows </a> (for me it doesn´t work neither) and on somewhere else the line mentioned in the link <strong>mount ${cowdevice} -t ${cow_fstype} -o rw,noatime /cow || panic "Can not mount $cowdevice on /cow"</strong> is treated differently, because the solution from ryan is remove mode=775 and the solution from that site was defining another variable $cow_cowopt=rw,noatime,mode=775 (or 755 I don´t remember) and after the if before that line I have put the persistence before the else (I'm searching again the web page if I found it I put the link) and in the line mentioned by Ryan I have to replace after the -o option for the new variable. In that page explain that the problem isn´t the mode instead something isn't there that avoid that persistence option were taked in account. Of course I did al that but again the initramfs, so no one knows a real solution, or I do doesn't something.

Forgive me if I have some mistakes I'm not english native speaker.

Does this bug still exist in Ubuntu 9.10 Karmic Koala?
Feisty and Gutsy are EOL now.

I was testing burned disks of current 8.04.4 candidate iso, karmic release iso & lucid alpha 2 iso with a separate USB device and this behaviour still exists (i.e. no state info is saved - no bookmarks or history in firefox, no saved files, etc).

I am setting this bug report to Fix Released as persistent mode has been working for quite some time and there have been no reports of this issue about recent releases of Ubuntu.

Changed in casper (Ubuntu):
milestone:	ubuntu-7.10-rc → none
assignee:	Tollef Fog Heen (tfheen) → nobody
status:	Confirmed → Fix Released

Tried it with Ubuntu 14.04.2. Persistence does not work out of the box. Works only when manually adding the boot flag `persistence`.

When building a custom LiveCD adding `export PERSISTENT="Yes"` in `/etc/casper.conf` works.

Bootable USB-sticks should be fixed by editing the `/boot/grub/grub.conf` that you will find on your USB-stick. Replace the following part

```
menuentry "Try Ubuntu without installing" {
set gfxpayload=keep
linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash --
initrd /casper/initrd.lz
}
```
with
```
menuentry "Try Ubuntu without installing" {
set gfxpayload=keep
linux /casper/vmlinuz.efi file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash persistent --
initrd /casper/initrd.lz
}
```
(the new thing here is the `persistent` flag).
