It does some other juggling, yes. Mostly to do with snapshotting and cloning and doing the trick to swap the roles of clone and original -- none of which would apply to your case with several zpools. >> >http://www.infracaninophile.co.uk/articles/install-on-zfs/ but there = are >> >several other treatments around. > I've had a look through those notes and you are still specifying > mountpoints for (eg) zroot/ROOT/9.0-RELEASE/usr - which implies you > wind up with multiple /usr's mounted. =20 Yes. That's deliberate, and /usr is treated as a special case, because I want to keep instances /usr/src and /usr/obj paired up with the BE built from them, and it makes things a lot easier if I can mount them early at /usr/src or /usr/obj in order to do the build.
