I just cloned my root partition (in anticipation of a dist-upgrade), changed lilo.conf and fstab (in the cloned partition) and ran lilo.
But alas the system won't boot from the cloned partition. I can see a few pages of unsuspicous kernel messages, then it just stops.
For some reason I tried to boot from the good partition, adding init=/bin/sh and again the system didn't boot and stopped at the same kernel message. This made be believe that "there is something wrong with init".
So I decided to turn the tables and passed init=/sbin/init when booting from the "bad" partition and this indeed worked - the system booted just fine.
But I don't understand what's going on here. Does anyone have an explanation for this?
Here's my lilo,conf

root=/dev/sda3
