On linux id do XFS on 64bit but I would add that you can skip formatting
your storage partition during installatioon and install the xfs utils and
kmod with yum after the installation on centos. ubuntu and debian can both
install to XFS but your root filesystem should not be on the same physically
volume as your backup data.
Watch out for hardware support with opensolaris. it is about 80-90%
compatible but I have a nack for owning that 10-20% of incompatible
hardware. Also, be very sure that you have a rediculous amount of ram for
ZFS. I'm talking 4GB+. Also, ZFS really wants a quad core, you know, 2 for
ZFS and 2 for your OS. And I highly discourage ZFS on *BSD right now as it
is just not stable yet.
