Yes, moving logic out of phablet-tools into the phone itself is
generally the right direction IMHO. But again, the logic is now in a
package which isn't installed by default. Also, the current
helper.unlock() thing is really involved -- it needs autopilot,
emulates a swipe, etc. This is of course fine for testing unity itself
-- but for everything else (app testing) we don't care about that. We
just want to get the phone from "virgin install" to "we can start an
app and test it" with the least possible effort and potential breakage
as possible.

So I think there ought to be a simple way (D-BUS call, flag file,
etc.) to either disable the greeter (and then have to restart unity),
or unlock it with a D-BUS call (not a security issue, you are already
logged into the device anyway).

Why is that? I don't want to restart the whole session, just unity8
within the session. Or possibly not even that.

Right. But remember that we want to get away from changing the phone
to r/w and apt-get installing packages. We can probably make
unity8-autopilot work with autopkgtest's "apt-get download, unpack,
and set $*_PATH" approach for readonly; I haven't tried that yet, but
TBH I think this is a very brittle path and about 1000 times more
effort than what should be necessary to get the lock screen away.

That seems fine, at least as long as we don't ship the phone by
default to require a password. So I think it actually might be what I
want :-)

Thanks,

Martin
