* Moved some scriptlets to the appropriate modules. * Put the scriptlet that sets the default path at the start, since it never makes sense not to have it there. It no longer needs to be declared as a dependency. * If a scriptlet has no dependencies, it can be denoted as a plain string (i.e., `noDepEntry' is not needed anymore). svn path=/nixos/trunk/; revision=23762
