If that were a problem, Linux would only have one filesystem.

Oh, absolutely.

I dunno about that. There's more of interest in a subsystem than just what

seem natural for EVMS to depend on device-mapper - but why is it necessary
to force the issue immediately, beyond hashing out a suitable interface?
