During my todays zypper dup run, I got this output:

( 72/408) Installing: libostree-2017.3-1.1.x86_64
......................................................................................................[done]
Additional rpm output:
Failed to disable unit: No such file or directory
Failed to stop ostree-remount.service.service: Unit
ostree-remount.service.service not loaded.

Is this a bug? The file is there:

> find /usr/lib/systemd/ -name "*ostree*"
/usr/lib/systemd/system/ostree-prepare-root.service
/usr/lib/systemd/system/ostree-remount.service
