Comment:

 This seems to break external mode in obfsproxy, because there is no state
 location set and we get:
 {{{
 |   File
 "/home/user/obfsproxy/obfsproxy/transports/scramblesuit/state.py", line
 64, in writeServerDescriptor
 |     assert const.STATE_LOCATION != ""
 | AssertionError
 }}}

 Maybe we should only do `writeServerDescriptor` only when in managed mode?
 Or maybe we should set the state location to a dummy value when in
 external mode?
