Note that there is no rate limiting on the log messages, so log_redirect

Allow a ppp startup option in rc.conf.
Adjust sysinstall so that it appends to the end of ppp.conf

get a list of interfaces, and then automatically configure them if
${ifconfig_${ifn}} or /etc/start_if.${ifn} exists.
This makes it a lot easier to deal with machines that constantly change
their network configuration as you can leave ifconfig settings for all
the possible cards - just the ones that are present will be configured.
Do discard standard output from the sysctl for approxy_all, and echo
what this sysctl is doing in the usual way. This fix is probably
backwards. We should probably just use the standard sysctl output
in all cases (it needs to have a newline filtered out).
Echo what the sysctls for nfs_reserved_port_only and nfs_access_cache

Despite their name it doesn't keep TCP sessions alive, it kills
them if the other end has gone AWOL. This happens a lot with
clients which use NAT, dynamic IP assignment or which has a 2^32

There is no detectable increase in network trafic because of this:
two minimal TCP packets every two hours for a live TCP connection.
Many servers already enable keepalives themselves.

log_in_vain:
log_in_vain turns on logging for packets to ports for which
there is no listener.
rc.sysctl:
A generic way to set sysctl values. It reads /etc/syslog.conf
and sets values based on that. No /etc/syslog.conf has been
checked in yet, and I've not added this to the makefile yet
until I get more feedback.

This is closely tied to Hellmuth's impending rc patches for ISDN, but

against the "master map" to get the list of mount point/amd map
correspondences, and using that list as command-line arguments to start

When I tried to do this with the existing /etc/rc* scripts, I found that
I couldn't do this by modifying only /etc/rc.conf: that file gets
sourced very early by /etc/rc, well before any networking functionality
is present, let alone NIS. Further, I wasn't able to figure out a way
to use various levels & types of quoting to defer evaluation of the
string to a point subsequent to NIS initialization.
As a result, I resorted to hacking /etc/rc.network -- but I did it in a
way that ought to be reasonably general, and avoid breakage for anyone
else.
