OK, here's a slightly editted diff from fbsd-stable9 to my tree.
I stripped out a little hardware specific code that diddles the
swap space size - it's not really generically useful to people.

Hopefully I didn't mess up the diff when I took that out.

A couple of notes:  I unconditionally setup a 4K gnop when
creating the zfs zpool.  It's kludgey, but I don't think it is
possible to get that effect through a command line option (yet).
Certainly if you want it to do this on freebsd-9 or freebsd-10
there's no command line way to do it.

The fstab that gets created for a zpool based system has a
commented out entry for / -- I have other mods in some of the
related scripts to key off that and "do the right thing" for
my purposes.  This could be improved.

Finally, I took a stab at supporting ZFS booting on sparcs.
There's a comment in there about the actual "dd" command that
needs to be done to make this fly.  I didn't do it.  I think
a general "installbootcode" command that could be built and
applied (similar to the way I built the gnop command) could
be made to work for doing this.  I'd really like this to
"just work" on sparcs too...

I didn't add any copyright to this mods, I don't know if the
changes deserve a mention or not.
