My main and default OS is still Ubuntu 10.04 on /dev/sda and with a separate home partition, plus, of course a swap partition which is used by all 5 OSs.

All these have /home in the root partition and then I simply link the data folders of my main Ubuntu OS to those in the homes of the other four OSs. I also link the hidden .mozilla and .thunderbird folders from the main OS to the others which gives me the same bookmarks, history, emails etc etc on all OSs.
