Ah, thanks for the clarification. I had assumed the tarball form the
squashfs-lzma site was patches.

You are right about that - but I later switched to using mksquashfs
from the 3.2 tarball, and tested the squashfs file by mounting it on a
2.6.23 kernel w/o problems.

When using mksquashfs from v3.2 I did not see those errors anymore. In
fact, there are no obvious errors anymore - attempting to boot we see

init=/sbin/init
root=CDLABEL=TEST_MINIMAL_f7_03
rootflags=
rootfstype=iso9660
root_ro=1
root_rw=0
Added udev rule 00-cdlabel.rules:
[some noise about udev]
SCSI subsystem initialized
starting udevd
creating devices
waiting for system to settle
no root yet, udev will write symlink...
waiting up to 60 seconds before dropping to emergency shell
-----
WARNING: Cannot find root file system!
-----
Create symlink /dev/root and then exit this shell to continue the boot sequence

I don't really know where to find the squashfs/ext3 file to try to mount it.

cheers,
