Dear all,

would it be interesting to port ofono from GDBus, which comes with the
huge GLib dependency, to sd-bus?
It is a lot of work, but the main question is whether we can assume
that systemd is deployed enough to allow the switch.

thank you for your feedback.

Best regards,
Giacinto

actually ELL provides its own D-Bus support. So the switch should towards ELL D-Bus and not sd-bus. oFono already links against ELL and at some point that should be its only dependency. We also want to remove the GLib dependency as well. Newer projects like iwd for example solely use ELL.

As someone said, ell already has dbus support.

But dependency on systemd would be bad -- I (and maemo leste project)
am running ofonod on Devuan -- which is Debian w/o systemd.

We are not introducing any hard-dependencies on systemd, so no worries 
there.  ell will eventually be used for all D-Bus communication and 
libdbus-1 dependency will be dropped.

If anyone wants to help convert stuff to ell, be my guest.  I've already 
done some bits here and there.

After the next release or two I will start requiring any new core code 
to start using ell.  Drivers might take a bit longer due to use of 
GAtChat/GRil/GIsi/etc.

it is a from-scratch and clean implementation of the D-Bus protocol. You currently don’t see it since the build magic in oFono only copies ELL pieces that it currently needs. However it is simple change in Makefile.am to also include ELL D-Bus.
