The general strategy is "don't do that". The reason being that such a
service file would never be acceptable upstream, as /etc/conf.d/ is
arch-specific. This means that we will likely have to change it again
in the future and it seems more natural to have the break now rather
than at random times later.
The ideal way to set things up is: don't use EnvironmentFile unless
you must. If you can, set up the service file so that it can give a
reasonable default out-of-the-box without further configuration.
Moreover, prefer configurations to happen in the native config files
of the service if they exist, rather than on the commandline. Lastly,
the expectation should be that in case the user/admin needs to tweak
the service file, this can be done by copying it to /etc/systemd/ and
editing it there, rather than editing a config file.
To be a bit less abstract:
* An example of where I could see no way but use EnvironmentFile is
for domainname.service in yp-tools.
* An example of where one might argue that an EnvironmentFile would
be useful, but where I think I found a reasonable way to avoid it is
