All functionality from the previous system has been preserved, and
users should still customize their system boot with the familiar
methods, rc.conf, rc.conf.local, rc.firewall, sysctl.conf, etc.
Users who have customized versions of scripts that have been removed
should take great care when upgrading, since the compatibility code
that used those old scripts has also been removed.
Instead, load them as part of the rc.d system. This allows us to prioritize
the initidiskless script so it runs before the configuration files are loaded
and allows us to get rid of the exit 2 hack in /etc/rc. The exit 2 never
worked anyway since it did not unset the prior configuration, causing the
diskless code to not operate properly.
Do a major cleanup and revamping of the diskless code for RCNG. This will
be backported to the non-RCNG scripts as well as -stable.

a per-machine or per-cluster (with different ways of expressing what's
part of a cluster) basis. In order for this to be effective, rc.conf
has to be reread after initdiskless is finished. Implement this by
adding a hook to etc/rc which rereads rc.conf by request. This can
also be implemented by renaming initdiskless to initdiskless.sh and
sourcing rc.conf there manually, but it was decided that, that would
be uglier than a hook in etc/rc.

under way to move the remnants of the a.out toolchain to ports. As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL. It has already lasted WAY beyond
that.
Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

portmap_* -> rpcbind_*
Also change single_mountd_enable to mountd_enable.
We also include shims for all the old variable names.

This could be improved by having the loader remove the record of
the next kernel to boot, it is currently removed in /etc/rc immediately
after disks are mounted r/w.

As an alternative to sendmail_enable=NONE, solve the boot time problem
for non-sendmail users completely by moving all of the sendmail startup
code from /etc/rc to /etc/rc.sendmail. The source for that script will
be kept in src/etc/sendmail/rc.sendmail so make.conf's NO_SENDMAIL will
prevent it from being installed. A new rc.conf variable,
mta_start_script specifies the script to run to start the user's
preferred MTA. For backward compatibility, it will default to
/etc/rc.sendmail. The specified script is called out of /etc/rc after
checking to make sure it exists. A new rc.sendmail.8 man page has also
been added which now houses the sendmail_* variable descriptions
formerly in rc.conf.5.
Use /etc/rc.sendmail in /etc/mail/Makefile to reduce code duplication.

Instead of rc.conf's sendmail_enable only accepting YES or NO, it can now
also accept NONE. If set to NONE, none of the other sendmail related
startup items will be done.
Remove an extra queue running daemon might be started that wasn't necessary
(it didn't hurt anything but it wasn't needed).
The new logic is:

# Do nothing

start sendmail with ${sendmail_flags}

at boot (sendmail_enable=NO), a localhost-only daemon may started
(sendmail_submit_enable) as it is needed to accept mail from command line
submissions. If this isn't desired, see etc/mail/README for more hints.
Optionally (sendmail_msp_queue_enable) start a queue runner for the
submission queue in case a daemon isn't available to accept command line
submitted mail at submission time.
Note that the syslog labels for all of these sendmail processes have been
uniquified for easier log parsing.
Checking for the existence of sendmail.cf is rather silly when someone
is using the mailwrapper(8) to run a mail daemon that is not actually
sendmail(8). It is also probably better to let sendmail(8) actually
try to start and error out if the administrator has
'sendmail_enable="YES"' but no sendmail.conf. At present, it would
fail silently.

This increases the scope for user error and also means that systems with
networkfs_types set in /etc/rc.conf will not benefit from changes to the

Instead, store the default list in /etc/rc itself and allow the operator
to append to that list by specifying her own list in networkfs_types.
Rename networkfs_types to extra_netfs_types accordingly, as the new name
better describes the purpose of the variable. Default the value to
