Oh, OK. I have been experimenting with running a witness, but when I try to run the command from the wallet command line, I get the error "unable to create a database lock" (or something similar, I am not in front of it)

That is why I can't get to the interface on peakd yet. I will keep troubleshooting when I get time. Thanks!

Unable to acquire database lock

Have you ever seen this error while running update_witness?
