Hi!

So far, to view the config file of sshd, elogind, etc., you'd have to do:

  cat /proc/PID/cmdline | xargs -0

or sometimes:

  cat /proc/PID/environ | xargs -0

and extract the config file name from there.

With this change, you can do:

  cat $(herd configuration elogind)

or similar.  Simple but convenient.

This patch series adds it to a few core services.  Adding it elsewhere
is left as an exercise to the reader.  :-)

Thoughts?

Ludo’.

Ludovic Courtès (3):
  services: shepherd: Define 'shepherd-configuration-action' helper.
  services: Add Shepherd 'configuration' action to various services.
  home: services: redshift: Add 'configuration' action.

Thanks for taking a look!

I pushed these patches with two minor changes: added the ‘configuration’
action to dicod, and documented ‘shepherd-configuration-action’.

  8b56983999 home: services: redshift: Add 'configuration' action.
  8d9647d8a7 services: Add Shepherd 'configuration' action to various services.
  ebc7de6a1e services: shepherd: Define 'shepherd-configuration-action' helper.
