Going back to FreeBSD from Opensolaris (Score 1)

I've been using FreeBSD for quite a while. I decided to jump ship to Opensolaris for ZFS when I brought up a new NAS server. Welp, with FreeBSD 8.0 out now, I'm jumping back. I've had a heck of a time getting apps to work on Opensolaris, the file system is impressive and works great, but if I can't run the apps I want to access the data, it's pointless for me.
