The problem I had with that is that it expects either fully-qualified
paths, which means we need to know where the package is going to be
installed (I mean, we do, but it seems brittle). Or it looks for
config relative to the VM working directory. If you're using the relx
start script, that's one up from the 'bin' directory.

And do you keep that 'priv' directory next to the 'bin', 'lib',
'releases' directories, etc.? That might work. Do you then deploy a
separate file into that location on a per-environment basis.

I didn't think eunit (even with rebar) could use a config file.
