Hi,
I'm wondering if it does any bad if ed25519 online keys are renewed (to) often (i.e. on every ansible-playbook run and the admin runs it 3 times in a row to get it to complete on all hosts).
If key renewal causes all existing connections to die I'll try to workaround the problem and make tor --keygen idempotent (replace the key only if its expiry changed).
the 'problem' solved itself (tor does not need HUP when it's keyfile changed)
