I don't know exactly either what to do right now. I think I do know
exactly what to do once Ulrich updates version.h 2.12.99 - check if
he branched release/2.12/master and it's up-to-date wrt. master^
and push it out if not, possibly wait another day or two to wait for
things to settle down finally, then tag 2.12.1 and upload a release
tarball - that all should be fairly well covered by:

What to do _before_ the release branch and master part ways, well...
who knows. :-) As I tried to explain the last mail, I don't see it as
a big problem myself since I consider the release to be still in -rc
quality state while it dwells in master and I'm not in a hurry (or
really care about the tarballs of the -rc quality release being
published properly); so my approach would be "just wait silently".
If others see a problem, they are welcome to propose solutions and

Ad who will volunteer to be the maintainer, I was prepare to open that
question when 2.12 leaves master, for precisely the reasons above;
I don't see a rush. Perhaps at some point, someone will really care
about being a maintainer (e.g. I'm very happy to be 2.11 maintainer
since it is important for SUSE, being in an enterprise distribution)
and will volunteer proactivel; at other times like now, we will look
around among ourselves when the issue becomes relevant to us (for me,
that is at the 2.12.99 time).

I _think_ Ulrich made the branch the last time, but I'm not sure.
For me, the key event is the commit updating version.h to .99, marking
start of development for next main version. It seems common-sense to me
to wait if Ulrich also pushes the branch around that time or do it
ourselves if that doesn't happen.

That is the definition I had in mind; I used a way too overloaded word
here, sorry about that.

I think it would be good to keep the tradition of keeping the release
branch in sync with master right up to version.h update to .99.

I agree; but I believe the process is clear, well-defined and hopefully
working for minor stable releases (we will hopefully confirm that with
2.12.2 now), just not for the major stable release. My argument is that
given the state of the major stable release, I simply don't think it is
a huge problem or one that should automatically be in competence of the
to-be stable maintainers.

However, there isn't too huge amount of work involved. If you think it
will be helpful, I will try to initiate the discussion about next stable
maintainer before the next main version is tagged, and suggest that they
prepare and upload the tarballs. It would be helpful if Ulrich just Cc'd
his announcement on info-gnu or it will be awkward to forward or quote.

It was in a P.S. to the 2.11.2 post.
