Failure when attempting to boot from stock configuration

Bug Description

I'm trying to use live-build 3.0~a24-1ubuntu17 on an updated install of Oneiric/i386.

The first example in the official documentation - <> - has a simple stock image to start with:

    mkdir tutorial1 ; cd tutorial1 ; lb config
    lb build

When I do this, I end up with what appears to be a working binary-hybrid.iso. When I boot it, it shows the Debian Live splash screen, and prompts me to enter "live" or "memtest" to run the livecd or memtest86+ respectively. Running "memtest" works, but if I type "live", it seems to do absolutely nothing. The splash screen does stay visible and I can still type in memtest or interact with isolinux, but it doesn't (visibly) try to load the kernel or initrd or boot at all.

I note that, in the tutorial1 directory, the file binary/isolinux/live.cfg looks like this:

    default live
    label live
            menu label ^Live
            menu default
            kernel /live/vmlinuz
            append initrd=/live/initrd.img boot=live config

However, the binary/live/ directory doesn't contain a "vmlinuz" or "initrd.img". It does contain:


Now, that's me matching the official *Debian* documentation with the *Ubuntu* package, so maybe there's another step that needs to be done since I'm running inside Ubuntu? If I missed that, please let me know.

I also wondered if the problem was that it generated two initrd images and two kernels. I tried to test for this: I modified the the auto/config file which 'lh' created so that it contained these lines:

    --architectures i386 \
    --linux-flavours 486 \

When I re-ran "lb build", it only created one initrd and one vmlinuz: "initrd.img-3.2.0-2-486" and "vmlinuz-3.2.0-2-486". However, the "live.cfg" file still was referencing a "vmlinuz" and "initrd.img".

Any help is greatly appreciated.

Did you use the livecd-rootfs auto scripts?

I have a similar issue trying to build a stock image using Raring.

The binary/isolinux/txt.cfg file contains the boot menu options with the names initrd.lz and vmlinuz like this:

default live
label live
  menu label ^Try Ubuntu without installing
  kernel /casper/vmlinuz
  append file=/cdrom/preseed/ubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash --

Nevertheless the names of the files inside the casper/ directory are: initrd.img-3.8.0-25-generic and vmlinuz-3.8.0-25-generic respectively.

So the bootloader can't find the files during boot time and shows the dialog message '/casper/vmlinuz' file not found, after pressing OK, it just stays in the splash menu.
