[SOLVED] `git fetch tag NAME' into mirror repo does not update HEAD, what to do?

I concur. However, the “refspec” in this case is the obscure
‘tag TAGNAME’ (where the ‘tag’ is a keyword); see get-fetch(1)
at the end of §OPTIONS where it describes “short-cut notations”.
That does not seem to accept a :<dst>, nor would I be too sure
what it meant if it did.

Point taken, I was being sloppy. We want the head of the
relevant branch (master) to be updated in our bare (mirror)
repository.

NO. ‘get checkout ...’ does not work in a bare repository.
(You can modify my trivial posted script to prove this.)
However, your comment got me to thinking. This _does_ work:
git reset --soft FETCH_HEAD
(And, I presume without testing, so would ‘... v2’ ?)
Given that git-reset(1)'s purpose is to change the branch's
head (or to change HEAD as I've been incorrectly describing
it), that does make sense.
cheers!
