Anyone used NILFS2?
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.

Have any of you used NILFS2 and have any failures or success to report?
