Why does this need to be created manually? Why not try to create it if
possible the first time there's a chance to use it, no matter what?
or, if "no matter what" is too aggressive, why not at least try to
create the ephemeral it if it's clear that the non-ephemeral location is
longer than the max socket length?
I personally like the simplicity and uniformity of "if /run/user/$(id
-u)/ exists and is writable, then we will use it for the socketdir."
What does GnuPG gain from having a known failure mode that requires a
manual fix?
