summary: Ensure "snap set core" works
details: |
Check that through the command `snap set core` the config
"service.rsyslog.disable" can be used to enable and disable the
systemd rsyslog service. Also verify that work the configs
system.power-key-action, ctrl-alt-del-action and
proxy.${proto} among others
