>I am going to use Certbot to generate my ssl certs. Where does bbbsd find them   
      
   Concatenate your key + certificate (with intermediates, if needed) as bbbsd.pem   
    and restart bbbsd. That's it.   
      
   # cat yoursite-key.pem yoursite-cert.pem > bbbsd.pem   
      
   Did you solve libssl.so.1.0.2 vs libssl.so.1.1? You could create that softlink   
   to bbbsd dir and use LD_LIBRARY_PATH. Something like:   
      
   # ln -s /usr/lib/arm-linux-gnueabihf/libssl.so.1.0.2 libssl.so   
   # LD_LIBRARY_PATH=.:${LD_LIBRARY_PATH} ./bbbsd ...   
      
   I'll try to find more time after I return my Toronto / Mountain View / San   
   Francisco trip. Currently in Toronto...
