Hi Tom,

I'm aware that it wasn't you who blamed me for spreading "unfounded
FUD", it was Oliver and at the same time he mentioned backwards
compatibility, inter-distro-compatibility, the feature that one command
does it all.

AFAIK Ubuntu's systemd implementation doesn't provide any of those
three advantages, it brakes all three advantages [1].

The wrapper-workaround-approach leads to misinformation [1].

The mess could be avoided without much work, e.g. for

http://packages.ubuntu.com/trusty/all/rtirq-init/filelist

The Ubuntu maintainer just needs to correct the location and add a
service file, but even if you would provide the service file and
corrected file locations for the maintainer, you can't contribute to
Ubuntu. It's recommended to get in contact with Debian maintainers.



[1]
For example:

Imagine you'll maintain your install, using a workflow that can be used
for a clean systemd install.

[weremouse at moonstudio ~]$ systemctl list-unit-files | grep alice
alice.service                          enabled 
[weremouse at moonstudio ~]$ systemctl list-unit-files | grep rtirq
[weremouse at moonstudio ~]$



Looks like rtirq isn't enabled, but de facto it's enabled.

[weremouse at moonstudio ~]$ systemctl list-units | grep alice
alice.service
loaded active exited    Alice PPPoE
[weremouse at moonstudio ~]$ systemctl list-units | grep rtirq
rtirq.service
loaded active exited    LSB: Realtime IRQ thread tunning.
[weremouse at moonstudio ~]$ systemctl status alice | grep active Active:
active (exited) since Mon 2015-08-17 22:55:32 CEST; 13h ago
[weremouse at moonstudio ~]$ systemctl status rtirq | grep active Active:
active (exited) since Mon 2015-08-17 22:55:33 CEST; 13h ago



Regarding backwards compatibility, there is no backwards compatibility
when using the service wrapper.
Please correct me when I'm mistaken, didn't the service wrapper in the
past do the same as /etc/init.d/foo status does?

[weremouse at moonstudio ~]$ service rtirq status
● rtirq.service - LSB: Realtime IRQ thread tunning.
   Loaded: loaded (/etc/init.d/rtirq)
   Active: active (exited) since Mon 2015-08-17 22:55:33 CEST; 13h ago
