DEV NOTES ---> maybe use this /etc/tor/torrc to have all toor config on HDD
--> needs /mnt/hdd/tor & with dirs: sys, lnd9735, web80 
--> all with chown debian-tor:debian-tor & chmod 700
--> update getpublicip script to use if available: cat /mnt/hdd/tor/lnd9735/hostname
--> Above activate LND tor service when LND is compiled for ARM with TOR service
