Sure. You can use the same trick used to put LILO on a floppy.
Create a partition, set it up with just enough of a root partition to
keep LILO happy, then use the -r switch to LILO when you run it.
Here, for example, is the output of find(1) on a boot floppy that I use:
.
./lost+found
./IDENTIFY
./boot
./boot/boot.b
./boot/message
./boot/mesg2
./boot/map
./boot/mesg3
./boot/boot.0200
./dev
./dev/fd0
./dev/fd0H1440
./dev/ram
./dev/null
./dev/sdc1
./dev/sda3
./dev/hda5
./dev/hda8
./etc
./etc/lilo.conf
./vmlinuz
There has to be enough in /dev for LILO to figure out how to write
its stuff; enough in /boot to support LILO, and an /etc to contain
lilo.conf
You would, in addition, need to have your kernels and initrd files
in this filesystem; my example has only one kernel and no initrd.
You have to be careful in lilo.conf, to refer to all files relative
to this filesystem, i.e. do NOT include the "/LILO" prefix in the
pathnames.
Suppose you've created this and mounted it as /LILO in all systems.
Then to install it you'd run
/sbin/lilo -r /LILO
And all would be well. LILO will chroot(1) to /LILO, and run itself
there.
One last warning: LILO puts signatures in its support files. You'll
have to be using the same version of LILO in all distros, or else
some of the distros won't be able to run LILO correctly.
