Yes, now that the point about mountpoints is brought up (via Alasdair's post), that is something to look out for especially for delegated dataset hierarchies for apps/data (possibly rooted not at the volatile zone root but in a separate tree). If your delegated datasets use common conflict-ey mountpoints like /var/log (applied relative to a running zone namespace), there is some trickery with the order and value of setting mountpoint, canmount and zoned properties - when you want to access the dataset straight from the GZ for population or NGZ for use (and especially if for any reason you want to re-access from GZ later, such as to migrate). In fact, here "zoneadm ... ready" can be your friend as it should mount all datasets into the zone's namespace (but not start any services) and you can then access that logical FS tree from the GZ directly.
