The most intriguing btrfs, zfs, etc., feature that I have never played with

You can't! They are read only. Great for consistent backups.
Sensible of ZFS.
But I thought btrfs *did* allow CoW snapshots, and nested snapshots, and
it seemed to me plenty of other footguns. I've never played with it, the
fact that for the longest time btrfs' fsck didn't exist or was
considered experimental or some such, was one of the things that always
scared me off.
-kb, the Kent who is scared of some things.
