I don't like mysterious lilo events. The Warning line (as you probably guessed) is harmless - it looks at System.map, seees your kernel has devfs support, and then opens /dev/sda and /dev/scsi/host1/bus0/target0/lun0/disc, or tries to. Since you don't have the devfs daemon running, opening the second one fails, and lilo understands this as 'difference', rather than a fatal error, so it continues. It looks like this problem may have already been adressed - this is from the changelog entries for 22.5.8: - Make VolumeID scan skip INACCESSIBLE drives (device.c) Trying with a newer lilo than you probably have (running sid on this laptop), I see that lilo tries to get volume id's from each of my partitions, so this is probably what's going on. Oddly, it doesn't appear to touch fstab, only mtab - are the devices mounted when this happens, or no? Maybe this was the change, the it went from reading fstab to readin mtab to see what drives are accessible. You can try investigating with strace -f lilo -v 2>&1 | less lots of output, but at least it'll give you a better starting point.
