[tor-relays] how to generate relay keys manually (before actually running the relay)

create a folder per tor instance:

mkdir future-relay1 future-relay2 ...


then invoke tor manually (this will just generate keys and exit after that):

tor --PublishServerDescriptor 0 --orport auto --list-fingerprint
--datadirectory future-relay1 --Log "err stdout"


tor --PublishServerDescriptor 0 --orport auto --list-fingerprint
--datadirectory future-relay2 --Log "err stdout"

...

In these folders you will then find the fingerprint that you can use in
MyFamily, so you don't have to touch your existing relays anymore once
you actually use these generated keys on new relays.

Make sure you take care of filesystem permissions when using these keys
on the actual relay.
