I'm afraid I disagree. "zpool status" does show device names.
What will happen if a pool is created on /dev/ada1p3, and then ada1
becomes ada0 on a different host? When I boot from such a pool, "zpool
status" will show diskid/XXXXXXXXXXp3 instead of ada0p3 or ada1p3.
Is this a problem? Yes it is, if for example you had swap on ada0p2 in
the original system, ada0p2 will not be visible in the cloned system
(buried under diskid/XXXXXXXXXX* or something).
