Both risks you mentioned are true.
Maybe we have to clarify these risks on the TorTP UI (also a manpage is
still missing).

We used this setting basically to avoid (during the boot) the question
about "encrypted hard driver unlocking" on computer with FDE.

Until now we never experienced this problem, but of course we can work
to fix it together.

I checked months ago and I don't remember worrying issues:

Is this a realistic scenario? I never experienced with _automatic_ swap
mount from an internal HD.
I will check this behavior. Is there any hack in Tails to prevent it?

It is very interesting, but I think we have more important priority at
moment.
We should deal with this in the future, maybe after the next release.

why not :)

Cool!
I would be very happy to help, even if only for triage.

Many thanks :)
