Another option would be to have /boot partitions for each OS (small --
500 MB max) and do everything else in LVM. This gives you the
flexibility to increase or decrease the size of the various filesystems
easily without repartitioning.
In a similar setup, I use cascaded/chain-loaded grubs.
I.e. I have a "master grub" /boot partition, which chainloads indivdual
"boot" partitions of other OSes.
I.e. my partitioning basically looks like this:
/dev/sda1 boot (master grub partition, contains only grub).
/dev/sda<N> OS<N>'s /boot
/dev/sda<N+1> OS<N>'s swap
/dev/sda<N+2> OS<N>'s /
/dev/sda<M> OS<M>'s /boot
/dev/sda<M+1> OS<M>'s swap
/dev/sda<M+2> OS<M>'s /
...
Due to the "smartness" of some OSes/Linux distros' installers, setting
up this is quite tricky. The advantage of this setup is that it keeps
all OS's bootloaders independent and avoids interferences between them.
I had used LVN for a long time in this kind of setup, but it has shown
to be more of a nuissance than being helpful and meanwhile removed it.
Shareing /home only works to some extend, because all OSes/Linux distros
carry some amount of incompatibility inside of their "per-user
configurations", which may cause problems when switching betwen OSes.
