You can now register multiple values per named hook, e.g. addHook preConfigure "echo foo" addHook preConfigure "echo bar" will cause ‘runHook preConfigure’ to run both ‘echo foo’ and ‘echo bar’ (in that order). It will also call the shell function preConfigure() or eval the shell variable $preConfigure, if defined. Thus, if you don't call addHook, it works like the old hook mechanism. Allowing multiple hooks makes stdenv more modular and extensible. For instance, multiple setup hooks can define a preFixup hook, and all of these will be executed.
