Previously i had this in /etc/lilo.conf (lilo-21.5-7)

boot = /dev/sda2
prompt
timeout = 300
default = Linux
change-rules
reset
vga=792

# XFS
image = /vmlinuz
root = /dev/sda2  
label = Linux
read-only

# LFS_3.1
image = /vmlinuz-lfs
root = /dev/hde3
label = "LFS 3.1"
read-only

# Windows 2000
other = /dev/sda1
label = "Windows 2000"
table = /dev/sda

I bet if went back to XFS code from around Feb 20th i can still use this
config without lilo overwriting the superblock on sda2...but i've put
lilo on MBR and i'm happy with the way it works now :-).

I would like to see this change in lilo -:) for one and it would save
some boot suprises about VFS not being able to mout partitions...

Paul
