Bug Found! Booting Gusty RC1 From USB stick

[mburris]

I am unable to boot the stock filesystem.squashfs (found on the Gusty RC1 CD at /casper) or a custom filesystem.squashfs I have created from my Gusty installation.

Through various different tests and troubleshooting methods I have isolated the problem to the initrd.gz that accompanies the Gusty RC1 CD.

If I take the initrd.gz and vmlinux files from a feisty install CD, my Gusty squashed filesystem will start (with some pretty major hardware issues, ie. no touchpad)

Basically I am using Grub on my USB stick to boot to {usb_stick}/casper/initrd.gz
from there the {usb_stick}/casper/filesystem.squashfs should be called but isn't.

Here is the casper.log file that shows the errors:

Unable to find a medium containing a live file system

So as you can see for some reason it is not looking for the live filesystem on my USB stick which is shows up in /dev as sda1

Has your bug report been confirmed or assigned to anyone?

hmm looks like I just needed to have the hidden folder .disk on the root of my USB stick. Appearently the new UUID stuff used by casper calls for it.

So as long as the file "casper-uuid-generic" contains the same UUID as referenced in {initrd_archive}\conf\uuid.conf then all should work well.
