The firstboot logic has an error which causes the filesystem to be
mounted readonly even though root_rw_mount=YES. This fixes the error to
ensure that the root filesystem is mounted rw as expected after the run
of the firstboot scripts.

improve boot performance; this produces arguably astonishing (non-)results
if /etc/rc.conf is modified during the boot process.
Since performance considerations make it infeasible to automatically detect
if the cached /etc/rc.conf parameters should be invalidated, provide a
mechanism for explicitly requesting that /etc/rc.conf be reloaded: Catch
SIGALRM and reload /etc/rc.conf if it is received.

These scripts, containing
# KEYWORD: firstboot
will only be run if a sentinel file (default: /firstboot, configurable
via the rc.conf ${firstboot_sentinel} variable) exists; this sentinel
file will be deleted at the end of the boot process.
Scripts can request that the system reboot after the first boot by
creating the file ${firstboot_sentinel}-reboot.
This functionality is expected to be useful for embedded systems and
virtual machine images, where it may be desirable to
(a) download and install updates which became available between when
the image was created and when it was "turned on";
(b) download and install packages which may be newer than those
which were available when the image was created;
(c) install packages which run binaries during their install process,
bypassing the problem of cross-architecture installs;
(d) resize filesystems to match the disk onto which a VM image was
installed;
(e) perform initialization tasks relevant to cloud systems (e.g.,
Amazon's Elastic Compute Cloud);
and likely to perform many other one-time initialization functions.
Document this new functionality in rc.conf(5) and rc(8). [2]

keep a list of the scripts run early, and use that list to skip things

This has the primary benefit of not skipping a local script that gets
ordered too early in the second run. It also gives an opportunity to
clean up/simplify the code a bit.
Use a space-separated list rather than the more traditional colon for
maximum insurance against creativity in local naming conventions.

Implement a quiet prefix, which will disable some diagnostics. The

An additional benefit of having a quiet prefix is that we can start
putting some of our diagnostic messages behind this knob and start
"de-cluttering" the console during boot and shutdown.

rc.initdiskless if necessary) are safe, and actually allow fewer files

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.

adding a hook to etc/rc which rereads rc.conf by request. This can
also be implemented by renaming initdiskless to initdiskless.sh and

be uglier than a hook in etc/rc.

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.
