Colord reports the device/profile(s) getting registered when CUPS (?)
wakes up about every 13 minutes, then I see the 30 second
timeout. This sequence happens throughout the day.

Again, this is odd when compared to another machine with the same
colord version and configuration, and neither has the system idle
settings in cupsd.conf:

Any additional sequences on machine 'debianx' coincide with print jobs
being queued, and not a specific interval such as the 13 minute interval
seen on 'dell2800'. Also, the cupsd process is running on debianx,
but not on dell2800. Both are invoked with 'cupsd -f' as specified
in the systemd service file.
Trying the 'SystemdIdleExit off' parm to see if it keeps
cupsd up and silences the colord chatter.
