Information about reverse dependencies is already tracked in local.sqlite, as is information about which shlibs packages either provide or require. It's much more efficient to use a RDBMS and keep all that information in one place than scattering it all over the filesystem. Look at pkg-query(8) for how to extract that data from local.sqlite -- or it's close cousin pkg-rquery(8) which does the equivalent for repository catalogues. If I understand correctly the situation you're trying to describe, then I think pkg(8) already does what you want. Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil.
