> Why not pass --ppa=$PPA/$DISTRO/$SILO to phablet-config writable-image instead of calling that seperately?

Well, I didn't check, but I was just assuming that phablet-config didn't support the $PPA/$DISTRO/$SILO syntax for PPAs, so I was working around that.

Even if phablet-config really does work on RTM, it's just calling add-apt-repository anyway. What benefit do we get from going through a middleman?

> I don't think --force-yes is necessary any more and might even be a little unsafe since we should be dealing with a PPA whose key we have received already.

Yeah I can fix that tomorrow, EOD now!
