[tor-relays] rm /var/lib/tor/keys/* before changing exit policy?

[Martin Kepplinger]

Really quick not too important question. When switching a relay to
become an exit node or the other way round, does it make sense to delete
/var/lib/tor/keys/* beforehand and start it over this way?

I was thinking, if the relay has the guard flag, it would make sense,
but maybe even if it doesn't. I don't know. I'll do it I guess.

thanks
