Absolutely agreed...

Maybe I wasn't clear enough, but indeed I meant the initial creation for
a user who is starting her first gnustep process/app (independent of the
NSColorList issue).

How should the expected layout be created?  An explicit program he needs
to execute (see 2.a. above ;-) ) or implicitly which means each process
needs to check if it needs to create them.  But, yes, NSPathUtilities
initialization is a lot better that +[NSObject initialize].
