Based upon my limited perusal/skimming of the fsck man page, this appears
to be undocumented behavior.
I shall be filing a documentation PR on this, because I'm a firm believer
that important aspects of behavior should be documented.

Should it perhaps do so?
The particular filesystem that wanted to check yesterday was most definitely
_not_ listed in my /etc/fstab file. But that was not an oversight. That was
by intent.
Also and separately, please correct me if I am wrong, but aren't BSD style
partition labels going the way of the dinosaur, now that we have GPT
partitioning available?
