Rails development on desktop Linux?

I've switched to FedoreCore 5 and RadRails, mongrel for by primary
development environment. I find it fast and reliable. If I could get
my wireless cards to work with it, I'd replace the Windows on my
laptop. ( still keep a windows box for pre-deployment testing if the
production environment will be a Windows platform).

Note: Just discovered that FederaCore6 is out, but haven't checked it out, yet.
