The default FreeBSD boot process is quite verbose with a lot of debugging information along with kernel messages. We may divide that boot process into several ‘screens’ or stages. First thing You see is the ‘BIOS’ screen of the computer manufacturer. Second  thing is the FreeBSD BTX Loader. The third one is the FreeBSD Boot Menu with eventual ZFS Boot Environments if You use ZFS for root filesystem and other options to select like Single User Mode for example. The 4th one is the system boot along with kernel messages in non-native resolution. In the middle of that stage screen switches to native resolution and continues to display kernel messages and services leading to the text prompt with login: at the end. There comes optional fifth screen which may be graphically started (x11) login manager like slim or gdm.

This verbose information is usually useful for servers but not that much for laptops and/or desktop/workstation systems. The UNIX philosophy is to not ‘say’ anything to stdout if everything is OK, so stdout/stderr should only be used when something is wrong … like on AMIGA, if anything is wrong then I want to see big red sign like [GURU MEDITAION] but if everything is ok, shut the … slience is golden 🙂

I really like Sun Solaris 10 approach here, that it boots with minimal information like its version and hostname into the login: prompt in less then 10 lines. The image below is from the first Sun Solaris 10 boot, so it includes additional OpenSSH server key generation information.

Unfortunately – despite what Oracle says – Oracle Solaris is dying, I gathered most of the information here – Oracle just killed Solaris/SPARC/ZFS teams – https://forums.freebsd.org/threads/62320/ – on FreeBSD Forums. The recent Oracle Solaris 11.4 release process along with public beta will not change that. Oracle Solaris will be kept in maintenance mode for the rest of its life, which is set by Oracle to 2034 currently. Pity because even BSD bits recently found its way into it Solaris, for example the OpenBSD PF firewall, there are some differences – Comparing PF in Oracle Solaris to IP Filter and to OpenBSD Packet Filter – https://docs.oracle.com/cd/E37838_01/html/E60993/pfovw-comparall.html – but there are differences between OpenBSD PF and FreeBSD PF too.

Back to FreeBSD – according to the project website – https://freebsd.org/ – “FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms” so why not tune the boot process to be more appealing on laptops/desktops? Below are the stages of the default FreeBSD boot process up to the login: prompt.

Not very lean to my standards. But with one parameter in /boot/loader.conf and 5 slightly silenced startup scripts its whole a lot better. Here are the modifications needed.

First add the boot_mute=YES option to the /boot/loader.conf file.

As we are here, You may as well add autoboot_delay=2 parameter to the /boot/loader.conf file to speed up boot process by 8 seconds. Default delay is 10 seconds.

% grep boot_mute /boot/loader.conf
boot_mute=YES
%

Next we will need to modify these startup scripts.

• /etc/rc.d/ldconfig
• /etc/rc.d/netif
• /etc/rc.d/nfsclient
• /etc/rc.d/random
• /etc/rc.d/routing

Here is the summary of the changes. In most cases its just adding 1> /dev/null or 1> /dev/null 2> /dev/null to not display unneeded information at boot process.

% grep -n -E '(1|2)> /dev/null' /etc/rc.d/* | grep -E 'routing|netif|ldconfig'
/etc/rc.d/ldconfig:40: check_startmsgs && echo 'ELF ldconfig path:' ${_LDC} 1> /dev/null
/etc/rc.d/ldconfig:60: echo '32-bit compatibility ldconfig path:' ${_LDC} 1> /dev/null
/etc/rc.d/netif:260: /sbin/ifconfig ${ifn} 1> /dev/null 2> /dev/null
/etc/rc.d/routing:70: eval static_${_a} delete $_if 1> /dev/null 2> /dev/null
/etc/rc.d/routing:97: static_$2 add $3 1> /dev/null 2> /dev/null
/etc/rc.d/routing:104: static_$2 add $3 add $3 1> /dev/null 2> /dev/null

The only exception is the /etc/rc.d/random which requires little more love.

% grep -n -A 8 'random_start()' /etc/rc.d/random
45:random_start()
46-{
47-
48-   # if [ ${harvest_mask} -gt 0 ]; then
49-   #       echo -n 'Setting up harvesting: '
50-   #       ${SYSCTL} kern.random.harvest.mask=${harvest_mask} > /dev/null
51-   #       ${SYSCTL_N} kern.random.harvest.mask_symbolic
52-   # fi
53-

Here are diff(1) patches if that way will be easier for you.

Now lets see how FreeBSD boots now after the modifications.

Its definitely not perfect, but a lot better in my taste.

Now lets login to desktop 🙂

I prefer not to use a login manager so I have an alias named x to xinit command. This way after I login I type x press [ENTER] and x11 desktop is started.

% which x
x: aliased to xinit ~/.xinitrc -- -dpi 75 -nolisten tcp 1> /dev/null 2> /dev/null

UPDATE 1 – FreeBSD 12.x

I recently tried FreeBSD 12.0-RC* versions and there is one ‘talkative’ script that also could be ‘silenced’ a little.

Its the /etc/rc.d/devmatch scrtipt.

Here is the needed patch to make it great again nice and clean again.

UPDATE 2 – The drm-kmod Silencing

Recently to get support for newer GPUs the drm-kmod meta port/package is needed. The thing is that if you add the /boot/modules/i915kms.ko (for Intel GPUs) to the kld_list parameter it will display following error message from the kernel even with boot_mute=YES in the /boot/loader.conf file.

Loading kernel modules:
Dec 16 11:08:03 t420s kernel: Failed to add WC MTRR for [0xe0000000-0xefffffff]: -28; performance may suffer

The syslogd is guilty here with its default configuration in the /etc/syslog.conf file. To make it silent (not print pointless messages) make this change in the /etc/syslog.conf file.

Now it will not print these pointless messages.

This applies both to 11.2-RELEASE and 12.0-RELEASE versions.

UPDATE 3 – Silence the Services Starting Messages

Thanks to the vmisev suggestion we can silence the FreeBSD boot process even more.

Just add rc_startmsgs=NO to your /etc/rc.conf file and reboot to see effects.

Here is already silenced boot process by my earlier settings.

After adding rc_startmsgs=NO to the /etc/rc.conf file the boot messages are cut in half.

Now its very close to Solaris/Illumos provides 🙂
