associated changes that had to happen to make this possible as well as
bugs fixed along the way.
Bring in required TLI library routines to support this.
Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.
This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).
The submitter has agreed to continue on and bring us up to the
1999 release.
Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.
Many userland updates were done to bring the code up to par with
the recent RPC API.
There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.
While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.
New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.
Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.
Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.

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.

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

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.
