Installation on multipath device in Fedora... Is it a joke?

I've just read that in Fedora 14 installation on multipath device will be supported. I installed SXCE b97 on zpool containing multipath device two years ago. And after this piece of news we hear that Linux is superior OS.... For desktop it is quite good, but after this news I can't imagine something like Fedora on my server. I'm interested is it a case for every Linux distribution. Does CentOS or Debian support installation on multipath device?
I'm rather shocked with this information. Solaris is dying but two years ago it was much better then today's Linux. I hope, Illumos Project will give us a reborn server OS.
