[ubuntu-studio-devel] Shouldn't rtirq become a systemd unit?

[Ralf Mardorf]

Hi,

below is how rtirq currently looks like for the systemd based Wily and
below that how a systemd solution could look like [1].
It shows the rtirq service file. Btw. moving rtirq to bin comes with a
convenient side effect, a user simply can run "rtirq status" by command
line, without a path or service wrapper.

Is there a reason that rtirq for Ubuntu Studio still is an init file for
sysvinit or upstart usage and the used init process is ignored?

What's the idea behind using systemd for the init process, but using
wrappers to start init files instead of systemd unites?

Regards,
Ralf
