Re: ext4 and reiser4 availability

 Well I mean, you wouldn't use a file system like XFS or JFS for a mail 
sever, you CAN but by and large you won't. I can see very specific cases 
where different file systems are great, I mean, they were built... however 
if I were able to configure the number of inodes on ext3 I think I would 
rather use that then resier by and large. just my opinion though. ~Ben
