Re: [Libguestfs] FYI, lvs.ml: Unbound value Guestfs.create

This is a good argument for avoiding sub-makes. On my list of experiments is to convert a project with non-empty SUBDIRS to build via a single top-level make that includes pieces from sub-directories. Improved parallelism via a complete dependency tree is one advantage, since tools that don't need libraries don't have to wait for an early library-build to finish before starting.
