Or if another disk is plugged in that appears as a lower numbered
device, for example making the disk switch from wd1 to wd2.

Apologies, poor phrasing on my part - I meant whole devices rather
than partition within a device - so wd4, ld0, sd3, as opposed to wd1e
or raid2f. I suspect wedges such as dk3 should be fine, but again,
better to give zfs the whole device. (on a note of light amusement I
have used all of the mentioned devices in zfs pools at least once :)
