In systemd, it's common that a D-Bus activatable service references
`SystemdService=dbus-$BUSNAME.service` instead the real service name.
Together with an `[Install].Alias=dbus-$BUSNAME.service` directive,
this allowed to enable/disable D-Bus activation without uninstalling the
service altogether ([1]).
Currently, when we install the RPM then `nm-priv-helper.service` is not
enabled, consequently the alias is not created, and D-Bus activation
does not work. I guess, we should fix that by enabling the service in
the %post section or via a systemd preset? Dunno.
Anyway. It seems that nm-priv-helper.service is more of an
implementation detail of NetworkManager. It makes not sense for the user
to interact directly, or to enable/disable D-Bus activation (because
that is how it works).
So, drop the alias.

Description=NetworkManager Privileged Helper
|
|
|
|
#
|
|
# nm-priv-helper exists for privilege separation. It allows to run
|
|
# NetworkManager without certain capabilities, and ask nm-priv-helper
|
|
# for special operations where more privileges are required.
|
|
#
|
|
|
|
# While nm-priv-helper has privileges that NetworkManager has not, it
|
|
# does not mean that itself should run totally unconstrained. On the
|
|
# contrary, it also should only have permissions it requires.
|
|
#
|
|
# nm-priv-helper rejects all requests that come from any other than the
|
|
# name owner of "org.freedesktop.NetworkManager" (that is,
|
|
# NetworkManager process itself). It is thus only an implementation
|
|
# detail and provides no public API to the user.
