Agreed. What external programs are called in the process is immaterial;
as usual in the UNIX world we have an embarrassment of riches. ;^)
So, let's define some baseline wishes here, then discuss how one might
go about implementing them. I'll try to list what I've seen here so
far.
o The ability to start and stop individual subsystems, and start/stop
all dependent subsystems.
o The ability to specify some sort of alternate configuration name on
system startup, for instance to move between an ethernet and PPP
configuration.
o The ability to add a package into the system configuration without
editing existing scripts; each package configuration file should be
standalone and self-contained.
Did I hit the high points?
I really think this is doable, if we can figure out what it is that
we're trying to do. So far, Robert Withrow's proposal with each
script providing a standard set of shell functions is looking pretty
promising.
