Chris,
As I said recently I'm thinking of installing Fedora 7, will it "play nicely" with my existing Slackware installation? Has anyone else here got two versions of Linux dual-booting on the same hardware?
I currently have debian and arch linux on my desktop system, (alongside hurd :D ). I'd be cautious of sharing the /home partition, just because it is likely that you will have different versions of packages on the two systems, which will mean different versions of configuration files, which could cause some entertainment.
Rob.
