Nice! Comments below inline.

I do trust you with that (or also landing smaller fixes in master). Curiously,
I'm only a member of https://alioth.debian.org/projects/autopkgtest/, not an
admin, so Ian or Zack need to add you (and perhaps turn me into an admin).
Until then, you can also push the tree to github or similar, where it's nice to
comment/discuss inline.

TBH, I wouldn't bother with adding new options to adt-run. It's been deprecated
for a while and I really don't want new deployments to use adt-run (I want to
drop it after the stretch release).

This is probably bikeshedding matter, but my feeling is that this new
option/variables should be --apt-series/SERIES/add_apt_series. I. e. if you
have "jessie-backports", then the release of that is "jessie", the pocket is
"backports", and the series is the combination ("jessie-backports"), AFAIUI?

Well done for unifying this, as this is being used for re-trying without
pinning in case of uninstallability, which isn't specific to series vs. pocket.

"_org" sounds strange (like a domain name), can you please rename to
apt_sources_list_d? Also, please replace that confusing ''' ''' line break
with '\n'.

The _info() suffix is superfluous, and the comment is confusing; please rather
say "release name which occurs first in apt sources". And, in this case it's
reall a release :-)

Can you please change the existing --apt-pocket documentation here to say
'from release-POCKETNAME;" to clarify the difference between a full series name
and a pocket?

Likewise, this shouldn't be touched any more. This is only to ensure that the
backwards compat stuff doesn't regress. It's a lot of code duplication, but it
will go away after stretch.

Oh, that's interesting -- I hadn't actually expected that you really want to
add all existing⎵sources and rewrite them for "unstable". This is certainly
wrong for the former "lib.ubuntu.com grumpy" as that is a different series than
the default "fluffy" one. It's debatable if this should be done for the
third-party repo, as they commonly don't have other series either. One could
argue either way, but this seems to be brittle in both directions.
FYI, Simon propopsed a more generic way to add an entire apt line in #851568,
which then would resolve any ambiguity like the ones above. The charm of
--apt-pocket is that it can stay a hardcoded value in a CI system, but the same
won't really extend for full series names. So maybe for this having an
--apt-source which gets the full line (maybe with some magic <mirror>
replacement from the existing apt sources) might be both more flexible and less
confusing?
Thanks!
Martin
