The assumption at work here is that you have exported the zpool from the = system that was using it. At that point, zpool import <poolname> with no = -f will work fine. It is only the special case of a zpool that was NOT = exported that requires the use of the -f option. I don=E2=80=99t see this as an unreasonable expectation. You unmount = non-ZFS (and under the covers ZFS) filesystems before moving them to = other systems. Why should we not be expected to export a zpool before = moving it ? Note that in the case of a crashed or failed or otherwise _unexpected_ = move of a zpool from one system to another you still need to force the = import. Just as you are forced to either fsck or replay journals on = non-ZFS filesystems before you can mount them.=
