Keeping track of health problems. Mostly under /var/log/.
These logs are created by syslogd (or syslog in earlier distros).
`alternatives.log’ has a bunch about other programs installing things around 5 times a day. This includes x-www-browser, which sets the default browser (supposedly - this doesn’t work on i3).
It also seems to update cursor themes, man files and `montage'.
`apport.log’ is empty.
auth.log' shows keyring prompot times, Gcr’ prompter and a lot about CRON, the `power button'.
