If you're looking for a flexible filesystem, try btrfs. It is quite nice. It still needs some help in the performance department, but given a recent Linux kernel (say, 3.2) it works wonderfully. I use its snapshots and COW functionality the most.
The only downside to it is that it sometimes is slowish when I do many writes in a short period of time. Also, fsync() still takes awhile, so applications that use it liberally, such as dpkg, can run very slow.* Things which use SQLite also suffer under heavy write loads.
For that reason alone, I wouldn't yet use it on a database server. I would use it on a read-mostly file server, however.

I'm very interested in NILFS2 and considering using it as rootfs. I
read some good reviews and seems to perform okay in benchmarks. The
automatic checkpoints/snapshots sounds like it could be useful. (I'm
thinking especially to see prior versions of files in /etc for
example.)
Have any of you used NILFS2 and have any failures or success to report?
Anyone used NILFS2?
