Subject: [PATCH] Low: libcrmservice: Handle systemd service templates.
|
|
|
|
These unit files (which have an @ sign at the end) expect to be
|
|
parameterized by an instance name. Not providing an instance name
|
|
causes the dbus lookup to fail, and we fall back to assume this is an
|
|
LSB service. If the user doesn't provide an instance name, just add a
|
|
fake one. It doesn't seem to matter what name is given for the lookup.
|
|
|
|
See: rhbz#2003151
