[Solved] systemctl lists several not found services

I always get this warning on boot:

arch systemd[1]: display-manager.service: Cannot add dependency job, ignoring: Unit display-manager.service failed to load: No such file or directory.

I thought I could just disable this service since I don't use a display manager, but it throws an error when I try to do so:

~ # systemctl disable display-manager.service
Failed to execute operation: No such file or directory

I have several other services that are "not-found":

~ $ systemctl --state=not-found --all
UNIT                       LOAD      ACTIVE   SUB  DESCRIPTION
auditd.service             not-found inactive dead auditd.service
display-manager.service    not-found inactive dead display-manager.service
plymouth-quit-wait.service not-found inactive dead plymouth-quit-wait.service
plymouth-start.service     not-found inactive dead plymouth-start.service
syslog.service             not-found inactive dead syslog.service

I figured out that I can mask them when disable doesn't work:

~ # systemctl mask display-manager.service
Created symlink from /etc/systemd/system/display-manager.service to /dev/null.

Is this the right way to disable services that aren't actually installed? Furthermore, why are these services enabled in the first place?

Re: [Solved] systemctl lists several not found services

Look at the output of find /etc/systemd and find the paths to thes link that are trying to start those services.  Delete the links by hand

I have very little in /etc/systemd:

~ $ find /etc/systemd/ -name "display-manager.service"

~ $ grep -r "display-manager" /etc/systemd/

There are however a couple of references in /usr/lib/systemd:

~ $ find /usr/lib/systemd/system/ -name "display-manager.service"

~ $ grep -r "display-manager" /usr/lib/systemd/system/
/usr/lib/systemd/system/graphical.target:Wants=display-manager.service
/usr/lib/systemd/system/graphical.target:After=multi-user.target rescue.service rescue.target display-manager.service

Re: [Solved] systemctl lists several not found services

If you don't want a display manager, you can change the default boot target (or just ignore the message):

# systemctl set-default multi-user.target

graphical.target is basically multi-user.target plus display-manager.service.

The other not-found services are only listed in After or Before lists. These do nothing unless those services are actually scheduled to be started.

Nice! That did the trick. I'll just ignore the other ones.
