I'll admit it's a hack. Partition is named "iso-nly", labeled according to the .iso label, is wu but *really* it's ro, and all it does is mark ESP "hidden" which you can toggle on/off and see how that affects my boot-path setup. What really happens, is I've protected the first 4GB of the disk (and I've done it on spinning rust as well, circled all my squares and lined 'em up to sectors). I picture it like a CD on top of a 45 on top of a stack of LP's, some of which are those square promotional LP's from bitd. Except the CD is bigger than the 45, and most tools just see the entire disk as ISO9660. Anyway, does Solaris care if the fs is ZFS?
If the zpool has a property named 'bootfs' set (which usually points to the rpool/ROOT/openindiana_whateverversion zfs filesystem), it will boot from there. Be aware that illumos based distributions don't use Grub/2 anymore, but the BSD UEFI loader which is installed via the installboot command (instead of installgrub).
Solaris Backup is a UFS thing, I thought.
No, I think the name means just that you could start a dd from s2 directly to a tape to backup the whole (SMI) disk (regardless of its contents). UFS is nowadays only used in the gzip-compressed bootarchive (aka initrd on Linux), the target system is then mounted from compressed iso images on the DVD (or CD for the "minimal" OI ISOs.
