Hm. Of these:

isInExpectedDirInfoDocs looks like it might once have done something useful.

configure and restart and wait_for_bootstrap are all in use; they are
invoked by name, from the command line, at the end of runConfigFile,
where it says `return getattr(network, verb)()`.

I think the rest are likely to be unused.
