rgrimes 01cb869dd8 This is the rc work as provided by pts, I will me makeing some additional
changes to it based upon other outstanding bug reports and commits made
after his work.

Comments:

(a) sysconfig is still used to do all configuration.  I was not going to
    change that out from under you.... a user never need edit netstart
    or rc* unless they're being very weird.

(b) rc.maint has been folded back into rc.  It is just unworkable as
    a separate chunk because of ordering bogosities

(c) netstart does what it says... it starts up enough of the network to
    get up,  it doesn't start every bloody daemon that might talk to a
    socket...  netstart ifconfig's the devices and sets up routing if
    configured to do so.

(d) nfs disks are mounted immediately after netstart completes

(e) syslog is started as early as possible (right after nfs) so that error
    messages can get logged to remote syslog servers properly

(f) named is started (there is an argument that says that named should be
    started before syslogd because if you are the dns server for your domain,
    you'd like named to resolve remote hosts in syslog.conf,  but this is
    a minority case and the trivial workarround is to put the syslog host
    in /etc/hosts or use an /etc/resolv.conf -- why? because you want syslog
    to catch named errors, which is a MUCH more important and likely occurance)

(g) NOW all of the rest of the network daemons such as the time stuff, RPC,
    NIS, NFS, Kerberos and inetd are started

(h) the rest of the generic stuff is done (cron/printer/sendmail)

(i) shared libraries are set

(j) /etc/rc.i386 is run (this does FreeBSD/386 specific stuff like ibcs2,
    xtend, and all of the syscons stuff
    (this is actually started as /etc/rc.`uname -m`

(k) the syscons stuff has gotten a serious cleaning to make it consistent
    with rc conventions

(l) rc.local has had the comments about syscons removed (they are not relevant
    to this file now) and the full name of the kernel has been restored to
    /etc/motd
