Having one root-suitable filesystem built-in makes it easier to do a lot of 
atypical boot configurations, which are becoming rather interesting thanks to 
virtualization.  If we're going to pick one, I think ext3 makes the most sense. 
  I don't see a lot of benefit to building in xfs, reiserfs, or jfs, and I think 
we should definitely keep ext4 modular in its current stage of development.
