I didn't read your message in detail but if are you asking if the "label
=2E.. removed" are valid when the device is opened from an "alternative"
entry point (e.g. ad0s1e instead of ufsid/4867d45fd3972203) then yes,
this is by design. The label is read from the file system metadata and
anything that opens that file system for its own use can change this
metadata - so the labels are removed.

(note that this is nothing special as far as GEOM_LABEL is concerned -
this is present in all types and forms of labels).

If you're complaining about the verbosity of the whole process then I
think you can set the kern.geom.label.debug sysctl to -1 to avoid these
messages.

The "modern" way would be to use the labels as device nodes for mounting
instead of raw devices - in this case they would "stay" when opened.
