On Ubuntu Core, one cannot run dpkg-reconfigure for one, so the file can never
be modified in practice, and additionally we do not want to allow all possible
datasources under the sun without understanding their use cases in Ubuntu Core.
Note that already on Ubuntu Core, snapd as of 2.45.2 will write a configuration
file zzzz_snapd.cfg taking priority over this file to restrict the set of
datasources to a safe one, so we do not strictly need to delete this file, but
it will be simpler if we don't have this file.
Merge pull request #114 from jhenstridge/make-dbus-session-d-writable
writable-paths: make /etc/dbus-1/session.d writable
When the snapd snap is installed on an Ubuntu Core 16 system, it tries to write dbus configuration to /etc/dbus-1/session.d, which is not currently writable. This PR adds that directory as a writable path.
