Ok, that's a start.  I ran zpool import, which showed zroot, and then
did zpool import -f zroot, which happily succeeded, and this blew away
all the / mounts, so that the situation for the boot image is the same
for the system disk.  That is, no / mounted directories are visible.
I've rebooted the install image and looked at mounting to an existing
directory but the mfs is read only.  Running

zpool import -o mountpoint=z1 zroot

replies 'property mountpoint is not a valid pool property', which is

Should I give up on this and polish my system installation technique?
