2.4 has integrated ReiserFS support.

ReiserFS primarily boosts performance when you have large numbers of 
small files in a directory (as a heavily loaded outbound mail server 
does).  However when all data is being sync'd all the time (as a mail 
queue is) then ReiserFS does not perform so well and may deliver less 
performance than Ext2.

One significant benefit of ReiserFS is that it is journalled and does not 
require a lengthy fsck operation after a power failure.

I would not recommend that you change to ReiserFS at this time.  All my 
most important data is on ReiserFS and I am quite confidant in the 
combination of the reliability of ReiserFS (which is not 100% but is 
getting close) and the quality of my backups.

However changing the file system type on a server is a serious operation, 
I suggest that you play with ReiserFS on some less important machines and 
then consider using it on servers once you've got a feel for it.
