I am thinking of doing a triple boot (SL, Debian and Win7). However because I am really doing this because I can (or at least attempt), it strikes me at some point I might decide I want to go back to all Snow Leopard. Now here's the thing; is it easy to increase the space of the SL install again if I decide to trash Win7. I'll build the space for Debian at the end as I am positive I won't be trashing that partition. So something like: Snow Leopard - 250GB Windows 7 - 125GB Shared Partition (probably NTFS) - 50GB Debian - 75GB The most likely partition to go is the Win7 one and I would like to either add it to Snow Leopard or the Shared Partiition. That is, I would like to increase the size of one of them.
