I have two linux distros on my machine, but cannot figure out how to
configure lilo to boot them. Searching on the web, I don't find many
answers just a few hints.

Here is my lilo.conf on the (for the time being) only bootable os:

prompt
timeout=50
default=rawhide
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
message=/boot/message
linear

image=/boot/vmlinuz-2.4.20-2.21
label=rawhide
initrd=/boot/initrd-2.4.20-2.21.img
read-only
append="hdc=ide-scsi root=LABEL=/ resume=force"


image=/debian/vmlinuz
label=debian
root=/dev/hda1
read-only
append="hdc=ide-scsi root=LABEL=/ resume=force"
initrd=/debian/initrd.img

/debian is a symbolic link to /mnt/debinstall which is mounted at my
debian root partition, i.e. /dev/hda1.

Some suggestions have been to install a single lilo boot loader on
each root partition's boot sector such that each individual
installation does not need to know about any other installation. Then
one should (somehow) install "master boot" something on the boot
sector of /dev/hda.

Not daring to destroy anything more on my machine, I haven't even
tried to figure this out. But is the following on track?

For each installation:

mount root partition : mount /dev/hdax /mnt
chroot to this partition : chroot /mnt
configure lilo with no prompt or anything: editor /etc/lilo.conf
run lilo: lilo
exit this root and umount: exit, umount /mnt

Then make a single master boot sector like the following:

boot=/dev/hda
other=/dev/hda1
label=linux1
other=/dev/hda2
label=linux2
...

Or is this approach far off? Maybe the single master boot sector
configuration needs more stuff in it?

Thanks for any input.
