Comment (by cypherpunks):

 Hi again, I did some further testing and found out that you can enable
 BOTH v2 and v3 onions by starting with v3, then comment out the version
 line and SIGHUP, then reinstate the version line and SIGHUP.

 Final hostname is the v3 onion, but both v2 and v3 will work.

 I ran these tests using 2 tor instances on different socksport, one to
 create the hidden service, and the other as a client to access the hidden
 service. I stopped and started the second tor to make sure that there was
 no dns caching or stale circuits lying around.
