[CentOS] Calling All FS Fanatics

For our mysql servers we use reiserfs, which we install via a kernel rpm.

We then install reiserfs-tools rpm, and do some work on /etc/fstab and
some mount commands to get it all functioning.

We do this for performance and redundancy.

The daemons you run will likely have a say in which filesystem you plan to
deploy, good idea to post to those lists as well.  e.g. "Squid performs
horrible on RAID5, and it doesn't use SMP, it likes ext3 just fine because
of how it works".

Names some daemons, you'll probably get alot of opinions from people
fairly close to their respective code-bases, or their shadowy minions ; )
