I agree these are the only reasonable options we have.

Ouch.

Cherry-picking these commits will not result in any difficult conflicts (it's
mostly about s/32/64/, and some jessie vs stretch test suite images). But there
could be issues with running 7.0a4 on Tails Jessie/i386 -- we haven't tested
the 7.x series at all on that platform. Still I definitely believe it quite a
bit more likely to Just Work rather than introduce issues we don't see on Tails
Stretch/amd64. So my feeling is that this should be an hour of work.

At least for me, locally, the only problem I see (after applying all unmerged
fixes) is that Chris' patch for #12567 seems to miss some case. I've asked for
an ETA of a fix. So assuming Chris is available, or I manage to identify and
fix the issue, it's looking really good. :)

A con for option A:
* Users will be prompted to do two updates within four days, which is a bit
much both in terms of nagging frequency, bandwidth usage, and pure
inconvenience.
I'd also like to stress (pun intended!) the fact that option A's "more work"
(as in an extra release, 2.12.1) is not so suitable at this time. I think we're
collectively exhausted, and should try to take whatever breaks we can.
Yup, I'm quite a lot in favor of option B.

[I might consider sabotaging option A by pretending, as a reproducible buids
person, that "Tails 3.0 will only be reproducible if we pick option B". Will I
have to? :)]

Huh, I thought we would stick
