[vwnc] Subsystem framework needs a "postrequisites" method

Terry,

You don’t need them.

You can add methods to an existing subsystem that has the <prerequisites> tag.  That method answers the subsystems that must be run first.  You can do this to existing subsystems providing the one you want to change isn’t already active when you load such an extension method.  I’ve been doing this since I converted my daemon startup logic to use subsystems in VW7.4.1 – a couple of years ago.

The subsystem framework appears to have been designed to be

pluggable. However, it falls short in one area. If one needs to insure that

a subsystem activates “before” an existing subsystem then the

#prerequisites method of the existing subsystem must be modified to

make it happen. If there were a #postrequisites method then modification

of the existing #prerequisites method would not be required.
