To add to what Matthew said: if FreeBSD uses a more recent version of
zpool, and you run `zpool upgrade` on FreeBSD, I presume that would be a
point of no return. And while I can't say for certain--since I've never
tried it--actively sharing a single zpool between two operating systems
might be a bit of a pain. You'd need to export the pool from one system
and then import it to the other on every boot, no?

In short, permanently moving a pool from Linux to FreeBSD shouldn't be
any hassle. Moving in the other direction, however...
