It's documented how to run dhcpcanon as a non-root user when systemd is not present via a wrapper: https://github.com/juga0/dhcpcanon/blob/master/docs/source/install.rst#for-advanced-users

It's also documented, the different strategies considered to minimize privileges: https://github.com/juga0/dhcpcanon/blob/master/docs/source/privileges.rst
