Ok, so the most safe way is taking "ghc-pkg list" except the packages
distributed with ghc. This means a "database" of packages which were
distributed with ghc (for each of its versions which existed on
archlinux) would need to be maintained. For example the list of
package.conf files from previous versions of ghc is such a database. But
we really need only the pristine (as installed) package.conf for the ghc
version we are going to replace. What about adding some commands to ghc
installation which would store-off a copy of package.conf file. Then we
could write a script which tells what needs to be recompiled with a new
The second best is probably to take "ls /usr/share/haskell" since almost
all haskell packages are distributed with cabal.
