Hi,

When we had a lenghty discussion about the I2P packages
importing/sourcing/whatever process on tails-dev@ a few months ago,
one of my (implicit?) assumptions was that we have not (yet) built
enough trust into kytv to allow them to drop file anywhere on the
Tails filesystem.

I'm sure they won't take offense of seeing me reiterating this, even
if it feels potentially hard to hear.

Based on the above, yes. That's why I have documented, IIRC, how to
check these packages to verify that they don't put files in any
unexpected place, and therefore should not affect (if I got it right)
users who don't opt-in to start I2P.

We actually import source and binary packages from kytv's APT repo.

Right, (very good) points taken. Once again, you demonstrate that you
have a waaaay deeper understanding of our test suite than me :)

/me crosses fingers, and hopes we can convert all these stateful
things to systemd units at some point, and then have a way to ask the
system under testing, from the outside, if this or that has been
completed already. I guess that for the notifications that are run
from some /etc-ish thing, it should be possible on Wheezy, but for
those that are run from the user session, we'll have to wait for
systemd to manage the user session too, which should be available (as
opt-in, IIRC) on Jessie. That could be yet another good reason to
migrate to Jessie faster than we did with Wheezy.

Thank you. I won't be able to test and review this before May 24, so
better nag bertagaz to take care of it (at least of the testing part,
if he doesn't feel comfortable reviewing the thing).

Makes sense.

No, let's not rewrite things now.

Thanks for the explanation. Please make this clear in the commit
message next time, which will save both of us some time :)

Definitely. This would perhaps be a good candidate for 2.0, as a way
to improve maintainability, and to allow us to run our test suite on
a CI server. Anyway, we'll discuss this at the summit!

OK... but I still don't get why some action is needed on Wheezy, or
rather, I don't get why no action was needed on Squeeze, given what
I've reported on #7056.

Cheers!
