Description CAI Qian 2009-01-28 07:46:43 EST
Description of problem:
If I used F10 to create a rawhide livecd. The livecd would not be able to boot,

SQUASHFS error: Major/Minor mismatch, older Squashfs 3.1 filesystems
are unsupported.

This was because the host was using squashfs-tools-3.4-1, while the livecd had 2.6.29 kernel with squashfs 4.0, which break the back compatibility.

It was also a boot failure when using 4.0 version of squshfs-tools to create a 2.6.27 kernel based F10 livecd.

SQUASHFS error: Major/Minor mismatch, newer Squashfs 4.0 filesystems
are unsupported.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. livecd-creator --config=/usr/share/doc/livecd-tools-020/livecd-fedora-minimal.ks
Actual results:
Livecd failed to boot in initramfs.

Expected results:
Livecd boot.

Yep, squashfs broke compatibility.  There's not anything we can do about this in livecd-tools.
Comment 3 CAI Qian 2009-01-28 10:54:48 EST
Well, how about to add a check for kernel version installed in livecd while running mksquashfs to reject incompatible attempts?
