Sarge with ext3, reiserfs (3/4?) or xfs?

[Jan Meijer <jan.meijer@surfnet.nl>]

Hi,

Before installing two new debian-sarge servers I've decided to re-visit my 
woody-decision on ReiserFS.  This time I wanted ACLs.

So ext3 would be rather out of the question, for multiple reasons.

Come ReiserFS and XFS into the game.  Which one to choose?  I've heard 
positive reports of fellow-admins on XFS and am not quite sure whether 
ReiserFS4 made it into Sarge.  Which would be needed to get ACLs.

So if there's anyone out there with experience with either ReiserFS4 or 
XFS with Sarge I'd love to hear it.
