[OpenIndiana-discuss] Installing one package triggered upgrade

I don't think that you should be able to have the rpool at version
5000 without installing from oi_151a5 media, or issuing a "zpool
upgrade rpool" or "zpool upgrade -a" manually after booting into
oi_151a5.  If these are not the case, then your rpool should still be
at version 28, and if so, previous boot environments should still work
(you can can activate the one you are currently booted into via the
package manager or beadm, and then a reboot should work, by not having
any changed packages).  It is not possible to downgrade a pool (so be
careful with zpool upgrade).
