Hmm, what does this mean for us:

• A new connection status dispatcher setup is provided, where users can provide custom scripts that will be called on bearer connect/disconnect events. This dispatcher will make the netifd integration in openwrt work much better, as we'll be able to report network-initiated disconnections cleanly to netifd.

  There are no default connection status dispatcher scripts installed, but it's suggested distributions make sure the following directories exist:

  • ${sysconfdir}/ModemManager/connection.d/
  • ${libdir}/ModemManager/connection.d/

I somehow blanked on that when reading the changelog. As I understand, if we don't expose it it's just a feature no one can use - not replacing any existing functionality.

I suppose what we need to do here is give users a way to provide scripts via the module.

Looks like it is a no-op when the directory does not exist:

I took the liberty of rebasing and further updating in hope it fixes #182618 but the test_ccwa_response still fails on that branch (maybe due to GLib update).

Confirmed that cherry-picking the glib 2.72.3 → 2.73.2 update breaks the tests on this branch.
