Nice. Is there any reason to prefer GPT labels over
glabel on the raw disk like so?

	NAME               STATE     READ WRITE CKSUM
	zfs                ONLINE       0     0     0
	  raidz2           ONLINE       0     0     0
	    label/disk100  ONLINE       0     0     0
	    label/disk101  ONLINE       0     0     0
	    label/disk102  ONLINE       0     0     0
	    label/disk103  ONLINE       0     0     0
	    label/disk104  ONLINE       0     0     0
	    label/disk105  ONLINE       0     0     0

Could GPT labelled disks be read on a Solaris host
without further modification?
