This protects users who insist on the bad practice of copying

that exhausts available file descriptors.
Several people have expressed interest in breaking this function

to avoid error messages printed on /var/log/messages.
Recently added "stf" interface has IFF_MULTICAST bit set,
because IPv6 don't work on non IFF_MULTICAST set interfaces
in current implementation.
But "stf" interface is multi-dest IPv6 over IPv4 tunnel, so
can't treat multicast packet with no special configuration.
On the other hand, tools like "rtadvd", "pim6dd", "pim6sd"
send messages on IFF_MULTICAST set interfaces by default.
So there will be many bogus error message on /var/log/messages,
that multicast packets sent to "stf0" failed.
So,
-strip "stf0" from rtadvd sending interfaces in rc.network6
("rtadvd" is a daemon used only for local subnet, so it
will never need to send its packets over "stf0" interfaces.)
-Add default configuration files for "pim6dd" and "pim6sd",
and disable "stf0" in those files.

-Comment out example sentences more completely
-Redirect error message of ifconfig output into /dev/null, to correctly

The isdnd is able to listen on a socket for isdnmonitor to connect to
it to remotely control it (similar to ppp and pppctl). When this is
enabled in the isdnd config file, it will fail currently because isdnd
is started before the network interfaces are configured.
It is necessary to move the isdnd start after the ifconfig of the network
interfaces, then this problem will not occur.
Changes are:
- rpc.umntall is called at the right places now in /etc/rc*
- rpc.umntall timeout has been lowered from two days (too high) to one
- verbose messages in rpc.umntall have been clarified
- kill double entries in /var/db/mounttab when rpc.umntall is invoked
- ${early_nfs_mounts} has been removed from /etc/rc
- patched mount(8) -p to print different pass/dump values for ufs filesystems.

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).

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.

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
