Generating custom FreeBSD installation media


Generating a custom -current memstick image without all the debug feature enabled.


Have the head source installed (I will use /usr/src as example).
If not, here is an example for synchronizing up-to-date head (-current) sources on /usr/src
svnlite co svn:// /usr/src

Customizing build compilation options

A little debug feature to disable on -current:
echo "MALLOC_PRODUCTION=yes" > /etc/src.conf

Building world and kernel

New we start the classical building of world and our customized kernel.
For information this step takes about 4 hours on my PC.
cd /usr/src
make buildworld; make buildkernel KERNCONF=GENERIC-NODEBUG

Generating install media image

Last step: Generating the install media.
Here is an example for generating memstick install media without port tree (long live to pkgng! neither doc):
cd /usr/src/release
make -DNOPORTS -DNODOC memstick

Replace "memstick" by "cdrom" (bootonly.iso and release.iso) or "ftp" for other media.
You can add a -DNOSRC option for avoiding to include sources too on the media.

Then copy the image to your usb key:
dd if=memstick of=/dev/da0 bs=64k

Cleaning your mess

Your system has lot's of file that you don't need anymore, here is how to clean it:
cd /usr/src/release
make clean
cd /usr/src
make clean

Xorg for FreeBSD on Raspberry Pi

Thanks to Ray, we have a working X11 drivers that works on Raspberry pi too.
Here is how to install it:
Download the latest Daisuke's Raspberry pi FreeBSD image (login/password: pi/ raspberry and root password: raspberry).
Unzip, dd it on your 8GB SD card, boot your rspie and configure your network (Internet access mandatory for downloading pkg).
Install USB mouse drivers:
cd /usr/src/sys/modules/usb/ums
make clean all install

Install pkg and declare the repository:
tar xf ./pkg.txz -s ",/.*/,,g" "*/pkg-static"
./pkg-static add ./pkg.txz

echo 'packagesite:${ABI}' > /usr/local/etc/pkg.conf
Install Xorg, scfb drivers and some X apps:
pkg inst xorg-minimal xf86-video-scfb xorg-apps 
Configure /etc/X11/xorg.conf:
Section "Files"
Section "Module"
    Load        "dbe"
    Disable    "dri"
    Disable    "dri2"
    Disable    "glx"
    SubSection  "extmod"
       Option  "omit xfree86-dga"

    Option    "NoDRI"        "True"
    Option    "DRI"        "False"
    Option    "DRI2"        "False"

Section "InputDevice"
    Identifier  "Keyboard1"
    Driver      "kbd"

Section "InputDevice"
    Identifier  "Mouse1"
    Driver      "mouse"
    Option      "Protocol"      "auto"
    Option      "Device"        "/dev/sysmouse"

Section "Monitor"
    Identifier  "Monitor"

    Identifier  "layout"
    Screen      0 "Screen" 0 0
    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"
Then a dummy ~/.xinitrc:
xterm &
xclock &
xcalc &
exec twm

And enjoy:
