Bug Description

Binary package hint: casper

I am not able to use persistent storage with the Live CD (natty-desktop-amd64+mac.iso from 2011-03-29.1) on a MacbookPro6.2. I suspect this to be a Mac problem, because Mac handles partitions differently.

I created an ext2 filesystem on a USB system, labelled it casper-rw and booted with the USB stick in.
/var/log/udev shows that the partition is identified, but it doesn't seem to ever get mounted. Files saved e.g on the Desktop do not persist.
I also created an ext3 filesystem on the local disk, in case it was simply a problem with the USB stick. This also did not work.

This is significant, because the standard method of making a bootable USB stick with some persistent storage does not work on Mac (for reasons that I don't understand). I.e. the only way it seems to have persistent storage with a live image is by having a live CD and and an additional USB stick.

This is casper-1.259

This is not a problem on kubuntu (kubuntu-desktop-amd64+mac.iso from 2011-03-29.1). Persistence works as expected. In this case, I used an ext3 partition on a USB stick and added 'persistent' to the boot options.

Needs to be restested with ubuntu-desktop-amd64+mac.iso.

As you later discovered, you need to specify 'persistent' on the kernel command line for this to work. Marking as invalid.

Changed in casper (Ubuntu):
