I am used to do "root=0301" on the lilo prompt to avoid that.
Right it works when devfs is mounted at boot (kernel config)
and you change the lilo.conf from:

image=/boot/bzImage
 label=linux
 root=/dev/hda1
 vga=3845

to:

image=/boot/bzImage
 label=linux
 append="root=0301 vga=3845"

or:

image=/boot/bzImage
 label=linux
 append="root=/dev/ide/host0/bus0/target0/lun0/part1 vga=3845"

Maybe the append= thing shortly spoken of in the devfs docu is important.
And at boot time _there are no symlinks_ !!

When init=/bin/bash fails, you prolly have an empty /dev on your root fs
(as usual when doing devfs) and automount _off_. Turn it on.
