It does seem to care after the pool has been imported. A few people
have been bit by hardware/BIOS/firmware updates which somehow changes
the device names across reboots, or consumer hardware which changes
IDs every time a removable device is plugged in. It is wise to export
the pool before flashing new firmware which might cause a change to
device IDs. If you are using USB drives and plug the cables into
different USB ports while the pool is still imported, then the pool
will refuse to work.
FreeBSD seems to cause more issues due to changing device names than
Solaris does.
