Description Simon McVittie 2017-07-24 20:14:21 UTC
+++ This bug was initially created as a clone of Bug #100344 +++

Following on from Bug #101354, we want to let short-lived container manager helper processes create a container with a lifetime and then get out of the way. In particular, Flatpak does not have a "supervisor" process once the sandboxed app is running, except for bwrap (which is minimal, sometimes setuid, and does not use D-Bus) and the flatpak-dbus-proxy (which, long term, we want to remove).

In Bug #101354, the container would stop listening when its creator falls off the bus. This is not suitable for Flatpak long-term.

The design we had at the GTK hackfest was to fd-pass in the read end of a pipe. Until it polls readable, the container server keeps listening. When it polls readable, the container server stops.

This can go in the named parameters a{sv}.
