* Got rid of a lot of "postInstall=postInstall" and similar lines in

builders.  These are redundant now.
* Inlined some trivial builders.
* Removed a few explicit setup-hook creations.  This is done
  automatically now if setupHook is set.
* Deleted the initscripts package.  NixOS doesn't use it anymore.
