Good advice -- thank you.
But it still sounds like Jeremy's assessment, "it's a bug", is
accurate. ZFS could certainly check for zero hostid. If zero, it
should /definitely/ display a diagnostic which encourages the admin to
use /etc/rc.d/hostid (or a printout of it). If zero, it /might/
additionally do some reads in case a likely-looking /etc/rc.d/hostid is
available, and display the hostid, perhaps even speculatively start
using it. It would save some needless "no datasets available" hair pulling.
