I'd really prefer avoiding having to resort to the above hack, even if
that means grafting dbus with a variant that is built to use /run
instead of /var/run.

The jami test still fails with the current v3 too, that still needs
investigation.

It's annoying that I keep running out of steam on this series; if you
can continue pushing it forward, I'll have a look!
