Yesterday, after three months of indecision, we finally decided on a Linux distribution. We’re going, not with the (essentially) industry standard Redhat, but with SuSE. The codebase is obviously virtually identical, and the featuresets are pretty comparable, and Novell (who bought SuSE January 2004) gave us an amazingly good deal. It’ll be an interesting exercise trying to get all of our Dev and QA stuff moved over in the next few weeks, and there are apparently a couple of vendors we’ll have to pressure to hurry up their SuSE support, but it’s nice to have this decision finally made.
Update 3-23: It didn't go as easily as expected.
