(as the uml is in testing, this seemed a good list)
I am running the testing distribution, and have been having problems
trying to get UML working.
When I run the images on a RH machine as host, they work fine. On
Debian, I get the following problems:
- Debian image, always says that the flesystem has problems and needs
fixing (even when copied from a vigin, working image).
- RH image, complains about INIT respawning too fast and locks up. A
subsequent kill/restart results in irrecoverably corrupted image.
All this is using a stock host 2.4.18-bf24 kernel, and the latest
testing UML packages.
Error messages follow:

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate
superblock:
e2fsck -b 8193 <device>
fsck failed. Please repair manually and reboot. Please note
that the root file system is currently mounted read-only. To
remount it read-write:
# mount -n -o remount,rw /
