I tried to start the resolver daemon by adding "-S 
/var/run/kresd/control/kresd.sock" but to no avail:

Mar 10 10:49:45 <daemon.notice> kresd[32252]: [system] incorrect 
value passed to '-S/--fd': /var/run/kresd/control/kresd.sock
[endless loop]

Just for completeness, that option is for passing open system sockets, e.g. like systemd's socket activation.  (which isn't done in our Linux packaging for years now)
