[gentoo-catalyst] Mounting squashfs fails

[gentoo-catalyst] Mounting squashfs fails

[lurker]

A few days ago I made a few small changes (just to the root overlay) to
a catalyst project of mine and re-ran from livecd2 stage. For some
reason boot now fails during init:

[...]
>> Mounting squashfs filesystem
mount: mounting /dev/loop0 on /newroot/mnt/livecd failed: Invalid argument
!! Failed to $1: failing back to the shell...
BusyBox v1.7.4 [...]

If I then, from the ash shell that you're thrown into, run "mount -o
loop -t squashfs /newroot/mnt/cdrom/image.squashfs /newroot/mnt/livecd"
I get the same error as above (invalid argument). Nothing appears in dmesg.

I've tried upgrading catalyst from 2.0.6 to 2.0.6.905, and genkernel
(the one used "inside" the catalyst project) from 3.4.10-r2 to
3.4.10.905, but nothing helps. Not that I expected it to do anything
since the changes I made since my last successful build cannot possibly
have anything to do with any of the bugs fixed in the newer versions.

How can I troubleshoot this further?

This is caused either by having an too-old kernel with squashfs-tools-4.0 or a 
too-new kernel with squashfs-tools-3.x. If you're using a >=2.6.29 kernel, 
you'll need squashfs-tools-4.0 to create the squashfs image.
