I've done it both ways, and both have their advantages (these days I don't
multiboot at all), but if you have just one /boot partition, at the very
least Ubuntu is able to leave the other OS's grub stanzas alone. I
wouldn't count on all of them to be so careful, but Ubuntu will auto-update
the parts between the "DEBIAN AUTOMAGIC KERNELS" tags, and not anything
else, so you keep the other OS's stanzas outside that part. If they have
some similar magic, you may be able to have a section for each OS.

Sorry, can't help with BSD.
