If you boot from another system, there is no other way to
import a pool than using "import -f". So, I guess it is
part of normal administrative tasks. You can read more here:

This works and always have worked as documented.
Renaming a pool also works as documented, that is,
doing "zpool import oldnamepool newnamepool". Except
for this corner-case. IMHO this is a very serious bug.

Best,
