Tux Machines (TM)-specific
I just completed the easiest operating system upgrade I've ever experienced: Ubuntu Edgy Eft to Feisty Fawn. I directed the entire process over VNC, and did not have to leave the GUI at any time. Only a single restart was required, I did not have to edit any config files, and there does not seem to be anything left to clean up.
I was occasionally asked to resolve a difference between an existing file and a proposed replacement, but I was able to click "Replace" for each one. Most of the packages were able to intelligently convert their config files to new formats and preserve old settings.
I only have a few complaints about the process:
In light of the 2006 Sun-Canonical partnership, Ubuntu 7.04 "Fiesty Fawn" will feature a complete, free-of-charge Java stack for its users. Whether they admit to it or not, both are facing some form [direct or indirect] of pressure/competition with Red Hat and its JBoss combo. Consequently, Sun and Canonical realize that even if they don't want to directly tackle the middleware market, there is value in providing a fully integrated Java stack, optimized for Ubuntu.
