We've tried to use Solaris 10 x86 and/or OpenSolaris a number of times
at work for projects with various whiteboxes.  Unfortunately we hadn't
planned ahead real well (the boxes were assembled with other things in
mind) and usually the SATA RAID controllers weren't supported.  That's
been my biggest annoyance. :)  Other than that, no real issue with
Solaris other than it's also rather annoying to set up over the
network.  I just want to be able to PXE boot into the installer and
point to a remote tree where the OS Is and GO!  Seems I have to do the
whole JumpStart add_install_client junk though... grr.

Fedora 11 Alpha/Beta is nice though.  I like btrfs so far.  It has a
long way to go but looks real promising as a potential alternative to
ZFS.  I really hope they add block level data deduplication at some
