Have netstart directly source sysconfig so that it stands on its own.
Do not source netstart in rc, run it with sh.
Rework the dangerous /etc/hostname.* so that it uses a variable with
a list of interfaces and a variable for each interface in that list.
The files /etc/hostname.* become obsolete with this change, the
information is now stored in /etc/sysconfig.
Source any /etc/start_if.${ifn} files so they can export things to
netstart (plans for future enhancements in this area.)
Obsolete /etc/defaultrouter, this is now down with $defaultrouter from
sysconfig.
1. Move all system configuration variables into /etc/sysconfig
2. Adapt other files to use it.
3. Add a host of new variables for micro-managing your system in various
ways. For 2.1, /etc/sysconfig will be machine-edited so that the user
doesn't even have to care at all about the various funny names we picked.
4. Enable dset. We won't get it debugged if we never use it, and no one
has said anything negative about it yet, so here goes!
5. Try to use one consistent style throughout.
