bananapim5 vs dns

[Robert Heller]

Wondering if systemd-resolved is being obnoxious?  I've have problems with 
systemd-resolved being bitchy about not wanting to talk to a local bind9 
server running on a local Linux system, and generally being a pain in the ass 
about handling DNS... *I've* generally disabled systemd-resolved when this 
happens, and things work much better with a good "old-fashioned" 
/etc/resolv.conf file.
