I like the idea of adding and svc.conf, IMHO one of the few redeeming
features of Ultrix. I want to put in a request to make the search order
settable on a file-by-file basis (like Ultrix) and also expandable so if
you want to distribute a new set of files you can add it to svc.conf (or
whatever) and select your method of distribution.
