Completely removing service from systemd

Sometimes it makes  sense to start service via crond @reboot option,  not via systemd.  See Cron and Crontab commands

How to completely remove service from systemd using systemctl? OpenSUSE

[Log in to get rid of this advertisement]
I want to completely get rid of plymouth-start.

I disabled plymouth-start and stopped it using systemctl, then used zypper to remove the package from the system.

It still shows up when checking with systemctl:

Code:
sam14:/home/keith # systemctl status plymouth-start
plymouth-start.service
Loaded: not-found (Reason: No such file or directory)
Active: failed (Result: signal) since Wed 2015-01-21 22:37:17 EST; 21min ago
Main PID: 225 (code=killed, signal=SEGV)
It is probably not doing any harm, but I'd like to remove it so it doesn't show up in systemctl at all. Reading the man page for systemctl has not revealed to me how to do it.

It still shows up when I list units that failed to load:


Code:
sam14:/home/keith # systemctl --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
plymouth-start.service not-found failed failed plymouth-start.service
Ideas? I'm using OpenSUSE 13.2.

Thanks,
Keith Ostertag

Don't know why you'd care, but looking at the unit definition in Fedora, looks like they allow a kernel option "plymouth.enable=0" to disable it.
Don't have a OpenSUSE system to check, but should be easy enough to see if it also applies there.

Thank you for responding.

I care simply because I should be able to completely purge it (or any program) from my system, agreed?

I subsequently got rid of that pesky error message by running mkinitrd for some other unrelated problem.

More subsequent reading of the man page suggests that

Code:
systemctl disable plymouth-start.service
should work, but I haven't had the chance to test that.

systemctl mask <unit> won't uninstall but will completely hide the service unless you later unmask it.

You have removed Plymouth already, all that is left is the .service file. You can simply remove that by hand, if you are bothered by it.

For future reference, look at the output of:


Code:
ls -l /etc/systemd/system/multi-user.target.wants
and delete any dangling symlinks for that .service
