well, lets see, you make no mention of same or different distribs.

if same distribs;
 same versions? different configurations?
 one for test? one for work?

regardless of intent, you should have separate swap partitions so you have
ability to sleep/suspend either with out effect to other. also, check fstab
so that neither has other's swap as you can/might over write resume info.

each linux '/' should have it's own /boot. if you mount inactive '/' in a
subdirectory of other, ie, /mnt/part1, /mnt/part2 you have ability to pick
one linux to maintain grub's boot sector for both or multi installs.

this is done by coping lines from inactive /boot/grub/grub.conf to active
/boot/grub/grub.conf. saves worry about chain loader, tho you still install
to inactive grub's '/' partition during initial install. when you have a
kernel update, simply copy in new lines and you are good to boot.

as in all cases of new kernels, leave old lines in event you have a kernel
failure and need to recover with previous kernel.

you can share a '/home' partition if you give same user of each install a
different home directory to log into. ie, myhome-f12, myhome-f13, or
myhome-wk, myhome-tst. also, user can/should have same name and user id to
make file sharing easier.

this works, as i am using such for 2 installs of scientific linux and
2 fedora installs.



peace out.
