ModemManager service

[root2185]

I see that there are runit and s6 service packages, in Artix repo, but no dinit service.
I made one and it didn't work, maybe because it is already running.
Something starts it and restarts it if I kill it.

Hi. First of all I think artix forum is better place to post your issue (forum.artixlinux.org).
I suspect that ModemManager got launched by your DE (like GNOME) or something else.

Yep, sounds like it is being started by DBus. The S6/runit services are most likely allowing to start it early, but that's probably unnecessary anyway.

Do you know how can I prevent that?
I'd like to use dinit instead.

I deleted /usr/share/dbus-1/system-services/org.freedesktop.ModemManager1.service and now the dinit service works, thanks.

type            = process
command         = /usr/bin/ModemManager --debug 
logfile         = /var/log/dinit/modemmanager.log
restart         = true
waits-for       = loginready

I see output in the tty.
Can I redirect it all to the log?

[mobin-2008]

Hmm, from ModemManager man-page (https://www.freedesktop.org/software/ModemManager/man/latest/ModemManager.8.html):

--debug Runs ModemManager with "DEBUG" log level and without daemonizing. This is useful for debugging, as it directs log output to the controlling terminal in addition to syslog.

I'm not sure it is related or not.

Right, with:

command         = /usr/bin/ModemManager --debug  --log-file=/var/log/dinit/modemmanager.log

It does not clutter the tty anymore.

I am worried about the log getting million of lines though.
Is it cleaned automatically after some time?

No, It's not I guess. but if you don't care about debug logs you can just send its log into /dev/null (--log-file=/dev/null) or use logrotate.
