[ubuntu-studio-devel] rtirq for systemd

[Ralf Mardorf]

Hi,

as it turned out during a request regarding lightdm [1], Ubuntu packages
should have completely migrated to systemd. However, even while
upstream, Rui provides a systemd unit, the Ubuntu packages for 16.04
and 16.10 don't provide a unit at all [2], but rely on
systemd-sysv-generator.

What is your opinion on that?

Moving it to /bin has got the advantage, that you never need to run

  /path/to/rtirq satus

you only need to run

  rtirq status

in addition there would no systemd-sysv-generator related issue
anymore and a systemd unit could be used. Not to mention, that getting
rid of this hybrid approach, it becomes easier to maintain an install.

Regards,
Ralf

I wonder why they rely on systemd-sysv-generator.

That's from upstream, Rui, the one who wrote the script, not Debian,
aka Ubuntu's upstream, http://www.rncbc.org/jack/rtirq-20150216.tar.gz ,
IIRC he's using Suse:

[Unit]
Description=Realtime IRQ thread system tuning
After=multi-user.target sound.target

[Service]
Type=oneshot
ExecStart=/etc/init.d/rtirq start
ExecStop=/etc/init.d/rtirq stop
RemainAfterExit=true

[Install]
WantedBy=multi-user.target



On Arch Linux it's moved to /usr/bin/:

[rocketmouse at archlinux ~]$ cat /usr/lib/systemd/system/rtirq.service
[Unit]
Description=Realtime IRQ thread system tuning
After=multi-user.target sound.target

[Service]
Type=oneshot
ExecStart=/usr/bin/rtirq start
ExecStop=/usr/bin/rtirq stop
RemainAfterExit=true

[Install]
WantedBy=multi-user.target



From the Arch PKGBUILD:

sed -e "s|etc/init.d|usr/bin|" -i rtirq.service



Debian doesn't provide it at all:

"File list of package rtirq-init in sid of architecture all

/etc/default/rtirq
/etc/init.d/rtirq
/usr/share/doc/rtirq-init/changelog.Debian.gz
/usr/share/doc/rtirq-init/copyright" -
https://packages.debian.org/sid/all/rtirq-init/filelist

I'll talk it over with the Ubuntu Studio team, instead of talking to
Debian packagers.
