Bug#896944: service: this wrapper script should pass additional options to systemctl(8) when using systemd

[WHR]

Package: init-system-helpers
Version: 1.48
Severity: wishlist
Tags: patch

The service(8) script should pass additional options, if any after '${ACTION}', to systemctl(8).

For example, if I run 'service rsyslog status', I would got:

# service rsyslog status 
● rsyslog.service - System Logging Service
   Loaded: loaded (/lib/systemd/system/rsyslog.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2018-04-26 07:49:06 UTC; 22min ago

           http://www.rsyslog.com/doc/
 Main PID: 12149 (rsyslogd)
    Tasks: 5 (limit: 4915)
   CGroup: /system.slice/rsyslog.service
           └─12149 /usr/sbin/rsyslogd -n

Apr 26 07:49:06 x systemd[1]: Starting System Logging Service...
Apr 26 07:49:06 x liblogging-stdlog[12149]:  [origin software="rsyslog…rt
Apr 26 07:49:06 x systemd[1]: Started System Logging Service.
Hint: Some lines were ellipsized, use -l to show in full.


The systemctl(8) has hinted an option '-l' to show those long lines; but when
I trying 'service rsyslog status -l', the output shows no different.


I wrote a small patch to support those options.
