I installed debian and it couldn't boot bk24 (kernel 2.4) at install, so I have
like 1 reiserfs partition (created afterwards, because at the time I had
10 gig free) and the rest are ext3. ext3 is VERY slow. I know, it's not
THAT slow, but... I have like 5 partitions on each disk, and 2 disks. So,
take off swap and reiserfs, like 6 at one time. Painful.

reiserfs is the filesytem that servers should use. It has the least latency
these days ;-) And it's quite stable.

The filesystem code wouldn't be much more complicated. The changes
needed for this would all be in a separate source file anyway. Most of the
complicated crap is all in the code for the datasystem that manages the
two filesystems that suddenly exist in the same space.
