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:
# MTA
if ${sendmail_enable} == NONE
# Do nothing
else if ${sendmail_enable} == YES
start sendmail with ${sendmail_flags}
else if ${sendmail_submit_enable} == YES
start sendmail with ${sendmail_submit_flags}
else if ${sendmail_outbound_enable} == YES
start sendmail with ${sendmail_outbound_flags}
endif
# MSP Queue Runner
if ${sendmail_enable} != NONE &&
[ -r /etc/mail/submit.cf] && ${sendmail_msp_queue_enable} == YES
start sendmail with ${sendmail_msp_queue_flags}
endif

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
list in /etc/defaults/rc.conf on upgrade.
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
'NO'.

The objection was that the right place for the fix is in mount(8).
Having looked at that problem, I find it hard to believe that
the hoops one would have to jump through can be justified by the
desire for purity alone.
Note that there are reported issues surrounding nfsclient kernel

to the general case.

fsck checking. Applying these changes (typically via mergemaster)
will cause your system to start running background checks on all
your soft update enabled filesystems (provided that you have
a kernel with the required functionality, e.g., one built since
the end of April). Please report any and all problems to
mckusick@mckusick.com (not mckusick@freebsd.org which I read
infrequently). See the comment above the fsck command in /etc/rc
for instructions on how to disable background checking should it
cause you too much trouble.
Several FAQs:
1) Can I reboot before the background checks are done?
Ans) Yes, when the system restarts the checks will pick up
where they left off.
2) Can a crash during checking corrupt my filesystem?
Ans) No, recovered resources are returned to the system using soft
updates which ensure that the freeing is done in a safe order.
3) How will I know if any background checks are being done?
Ans) Filesystems that are to be checked in background will be listed
as `DEFER FOR BACKGROUND CHECKING' at the usual fsck check time
during system startup.
4) What happens to the output of the background checks?
Ans) It is sent to syslog `daemon' facility log level `notice'.
5) When will this feature be available in the 4.X kernel?
Ans) Never. It is much too radical and extensive a change to be
MFC'ed. Besides, it needs many months of experience and
tuning before it is ready for widespread use.
6) What happens if a background fsck fails (i.e., fsck finds
errors that would normally require a manual fsck)?
Ans) The filesystem will be marked as needing a manual fsck.
At the next system reboot, the check will be done in
foreground and the usual actions taken (usually a failure
to go multi-user until fsck has been run by hand on the
affected filesystem).
/dev/log like this: if [ ! -h /dev/log ];
