Thanks Rich. I had not seen that other thread.
And thank you, Althalus - it looks like you are right about omitted files. I'll probably play with it a bit over the long weekend and see if I can pull in the missing files - maybe figure out what needs to be added to the extension.
Its particularly frustrating because what I really want is to just edit the config file! But there's no documentation beyond "oh, just run cherokee-admin - you should never edit the config file".
