Are there any security concerns if multiple copies of a single Tor installation are used simultaneously? I ask this question in the context of virtual machine images or containers.
Worded differently, does Tor generate secret information that should not be made public upon installation or first run? (like openssh)
If you're not a relay and if you're not hosting a hidden service, then you can run multiple instances with exactly the same config.
If you are running a hidden service, then each introduction point will use the one that it heard about last. All instances should function though.
If you are running a relay, then each instance must have its own unique keys and fingerprint.
