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.

Ahhh, rather, display a diagnostic which encourages the use of "zpool 
import -a".
