One option might be to make the ghc-doc postrm purge check that the directory is empty and bomb out if it isn't. But I'm not sure whether this cure (blocking purge of a package with no configuration etc.) isn't worse than the disease (a leftover cruft empty directory). > Theoretically, the correct solution is to undo the symlinking and moving > the files back when ghc-doc is removed.

It will be very fragile, as you say. > Current code at > http://anonscm.debian.org/darcs/pkg-haskell/ghc/ghc-doc.postinst.in That looks plausible.
