Hello,

If you add the option ProtectSystem=yes to the service file, then the
daemon will not have the ability to write to /usr.

There is no reason why it needs to write there, so enabling this
option should not cause any problems.

This option is one of the systemd security features for systemd
service files that was detailed in a talk[0] given by Lennart which
details various security features you can enable in your package's
service files.
