Interesting stuff. Goes further than my requirements (I just did it myself, then concluded it was trivial :-) Had a look at that page, though, and there were some interesting points raised. (Personally, I'm a fan of the sysV runlevel system.) I'm not entirely convinced that points (1) "It should be easy for an administrator to get an overview of what is started and in what order" and the dependency-based topological sort are not diametrically opposed. I've often thought the latter would be nice (providing the "normalised service descriptions" are human-readable) but I'm not completely conviced that building startup scripts off the back of make is really desirable. So in rebuttal: I keep on hearing that FBSD expects a bit of savvy (in so many words) from its users. Certainly I'd expect it of an admin. The rc?.d/[SK]* idiom from sysV seems to be a useful piece of functionality (easy to manage with obvious gains); service dependencies must be sorted out by the admin, admittedly, but I'd expect an admin installing a startup script to have READ THE DOCUMENTATION and to have a good idea of how said service will interact with the rest of his system. chkconfig is admittedly very handy too. A full topological sort of services on startup smacks of feeping creaturism. jan PS.
