I think this commit has broken booting from mirrored zpool when raidz2
pool is exist.  In my setup it was 4 disks:

Where da?p2 are in a mirrored zpool and da?p4 are in a raid-z2 pool:

  pool: startpoint
 state: ONLINE
 scrub: none requested
config:

	NAME        STATE     READ WRITE CKSUM
	startpoint  ONLINE       0     0     0

It looks like that the gptzfsboot can recognize the mirrored
'startpoint' pool and load loader correctly (when I specify loader.old,
it worked just fine) but the loader can not.  I've tried to
