CrunchBang Linux

greetings, new guy here -- i was installing waldorf alongside a couple other already installed linux systems, but hesitated when i got to the part where the partitioner said i needed to go back and create a swap partition - this surprised me, as on this netbook w/1gb of ram, i have an already existing 2gb swap partition, which was displayed by the partitioner  -- and until now, the systems have all been happy sharing the one swap partition -- is there some reason why #! can't share a swap partition?
