How would you boot back to a ZFS snapshot if your update trashed the current BE? That's exactly what a BE is for (and it's little more than a ZFS snapshot anyway).
Well, to be pedantic - it is a bit more than a snapshot of the ROOT/bename(/*) dataset hierarchy (in general): it is a ZFS clone (set of clones) based on these snapshots ;) And also it is a change in GRUB entries and/or "bootfs" property of rpool. There's little to no more magic that I've discovered with my tests regarding hierarchical datasets for root BEs (detailed in illumos bugtracker as https://www.illumos.org/issues/829) and the system is quite sturdy compared to LiveUpgrade that it used to compete with in my Solaris 10 and Osol SXCE systems - LU needed a lot more manual massaging to work properly in my setups ;) My 2c, //Jim Klimov _______________________________________________ oi-dev mailing list [email protected] http://openindiana.org/mailman/listinfo/oi-dev
