(0) the git rename doesn’t really work when applying the diff with 
FreeBSD’s patch so the mv has to be done manually

(1) the rtsol Makefile also needs cap_syslog and util to link to 
otherwise rtsold.c has unresolved symbols

(2) rtsol seem to have worked when manually invoked;  /etc/resolv.conf 
was created (I had rm’ed it) and the 3 nameserver lines re-appeared;  
sorry can’t test the search string here

(3) rtsold crashes:
