Most daemons I know of that need to bind to ports <1024 start as root and after binding to the port they drop privileges to the privileges of the user specified in their config file. For those daemons just adding a user and specifying it in their config file should be enough. For the daemons that don't need to bind to <1024 just starting them from their own user account is ok as they don't need additional privileges. For example the dnsmasq daemon has these options: # If you want dnsmasq to change uid and gid to something other # than the default, edit the following lines. #user= #group= I don't think that integrating such functionality in ubus or some other LEDE-only super-daemon is a good idea. Config options + capabilities for those daemons withut such options is a good way of doing this in my opinion. Also use different users for different daemons, as others said.
