Yes I think we should not expose vg_write to library users. The fact
that it is created as an in-memory struct that is then extended to
include its first pv and then written, doesn't need to be exposed since
skipping any of those steps is incorrect.
So I'd like to see lvm_vg_create take a single path to a vg as a
required parameter. I don't think we need to take multiple pv paths, we
can extend to them after lvm_vg_create returns easily enough.
