[arm-allstar] Found updatedb to be running daily

[Danny K5CG]

Or you could slow it down to once a week, for example...

systemctl edit updatedb.timer

add the following text...

[Timer]
OnCalendar=
OnCalendar=Weekly

Save the file (automatically created here: /etc/systemd/system/updatedb.timer.d/override.conf)

Restart the timer...

systemctl restart updatedb.timer

Check the schedule again...

systemctl list-timers

NEXT                         LEFT        LAST                         PASSED UNIT                         ACTIVATES
Mon 2021-03-29 00:00:00 CDT  6 days left Mon 2021-03-22 00:00:14 CDT  9h ago updatedb.timer               updatedb.service

Maybe weekly is often enough.
