#ZFS is nice. I've had it, with full root-on-ZFS, since PC-BSD. It took me several years to actually realize how nice it was.

If you want something more arcane than #FreeBSD to play with, take a look at #Illumos, in particular its derivatives #OpenSolaris, #OmniOS, #SmartOS, and @ptribble 's #Tribblix.

Illumos has original Joy+Horton #vi (not one of the clones), the SMF, zones, ZFS, and a fair number of System 5isms not in the BSD world (e.g. sar, which @rl_dane was talking about the other day).

And, if you're up to that and not there already, feel free to visit #illumos and #smartos at LiberaChat IRC
