Tor controller GUI (tor-control-panel)

[Patrick]

Packages are forbidden from editing other package owned configuration files. (Exceptions might exist but not appliable here.)

/etc/torrc.d must be used.

But Debian 2017 feature request add torrc.d configuration directory stalled sonce 2019.

If the tor-control-panel package doesn’t modify Tor owned configuration file /etc/tor/torrc, that’s acceptable by Debian.

tor-control-panel GUI is allowed to modify /etc/tor/torrc any any other file in $HOME etc. Other example GUIs in Debian are doing that. (Examples: gufw, synaptic, software-properties-gtk, grub-customizer. I think.)

Do you want to support configuration of both, system Tor and TBB installed in $HOME?

As for Tor (Browser) configuration files try asking me. For example system Tor not causing conflicts with TBB will be easy to answer.

Note.

DisableNetwork 0|1

When this option is set, we don’t listen for or accept any connections other than controller connections, and we close (and don’t reattempt) any outbound connections. Controllers sometimes use this option to avoid using the network until Tor is fully configured. Tor will make still certain network-related calls (like DNS lookups) as a part of its configuration process, even if DisableNetwork is set. (Default: 0)
