I just upgraded following machines to ubuntu 9.10:
- debian 5
- ubuntu LTS 8.04
- ubuntu 9.04
so now for all debian-like distro I’m running pure Ubuntu.
Fedora will release 12 in mid-November, I will “upgrade” both centos and fedora 11, and after that I will keep running both Ubuntu and Fedora, as my Linux platform, 50-50.
