None of this information makes any difference: Danny's original analysis
of the problem is correct. Any zpools which show up after /etc/rc.d/zfs
has run will not be automatically mounted, they must be explicitly
mounted with 'zfs mount -a'. This is expected behaviour, and how things
are supposed to work, but noone had previously realised that iSCSI disks
(and, presumably, any other networked block devices) necessarily fall
into this category. The solution is a ZFS equivalent to
/etc/rc.d/mountlate; I believe all it needs to contain is 'zfs mount
-a', but ICBW.
