systemctl shows 'errors'

[Alexander Volovics]

Investigating systemctl I came across the following:

systemctl list-units --type=service --all |grep error

dbus-org.bluez.service    error  inactive dead  dbus-org.bluez.service
livesys-late.service      error  inactive dead  livesys-late.service
openct.service            error  inactive dead  openct.service

The number of services listed with LOAD = error is not constant.
Sometimes I have seen more.

Is this 'standard' behaviour or something that needs correcting?
