=Build Own Generic CD=
<pre>
mkdir -p /usr/local/etc/cvsup
cp /usr/share/examples/cvsup/cvs-supfile /usr/local/etc/cvsup/ncvs
</pre>
Edit the file:
<pre>
*default host=cvsup5.de.freebsd.org
*default base=/usr
*default prefix=/home/storage/ncvs
*default release=cvs
*default delete use-rel-suffix

# If your network link is a T1 or faster, comment out the following line.
*default compress

# Add these
src-all
src-crypto
src-eBones
src-secure
src-sys-crypto
ports-all
doc-all
#www

cvsroot-all
</pre>
Now checkout the sources:
<pre>
mkdir /home/storage/ncvs
cvsup -g -L2 ncvs
</pre>

Now compile your own system:
<pre>
cd /usr/src
make buildworld
</pre>

Create now the release files:
<pre>
cd /usr/src/release
/etc/rc.d/adjkerntz start
adjkerntz -i
make release CHROOTDIR=/home/storage/ownfreebsd BUILDNAME=test \
CVSROOT=/home/storage/ncvs RELEASETAG=RELENG_6 MAKE_ISOS=1
</pre>

= Build a Custom CD =
Delete /usr/src and check it out from your local repository:
<pre>
cd /usr
rm -R src
mkdir -p /usr/src
cd /usr
cvs -R  -d /home/storage/ncvs  co  -P -r RELENG_6 src
cd /usr/
cp -pR src src.orig
</pre>

Then apply your changes to /usr/src (kernel config files, patches everything you need).<br>
We will use a unattened install procedure to install the own build kernels so we don't have to modify the sysinstall package.<br>
To use our own install script edit:<br>
* /usr/src/usr.sbin/sysinstall/Makefile

and add:
<pre>
CFLAGS+= -DLOAD_CONFIG_FILE=install.cfg
</pre>

Now create a install.cfg file in /usr/src/release for an example see here.

Create a directory for own packages that will be included to the CD:
<pre>
mkdir -p /root/ownpackages/disc1
</pre>
Now copy all packages to the directory /root/ownpackages/disc1.

Make a diff with:
<pre>
cd /usr
diff -Nur src.orig src >/root/patch.diff
</pre>

You can try if the patch works with:
<pre>
mkdir -p /home/storage/ownfreebsd/usr
cd /home/storage/ownfreebsd/usr && cvs -R  -d /home/storage/ncvs  co  -P -r RELENG_6 src
patch -s -d /home/storage/ownfreebsd/usr/src  < /root/patch.diff
</pre>

<pre>
cd /usr/src
make buildworld

cd /usr/src/release
make release KERNELS_BASE="I4B I4BSMP GENERIC SMP" \
CHROOTDIR=/home/storage/ownfreebsd BUILDNAME=FreeBSD-I4B \
CVSROOT=/home/storage/ncvs RELEASETAG=RELENG_6 MAKE_ISOS=1 \
CD_PACKAGE_TREE=/root/ownpackages \
KERNEL_FLAGS=-j4 WORLD_FLAGS=-j4 \
LOCAL_PATCHES=/root/patch.diff PATCH_FLAGS=-p1 KERNELS="I4B I4BSMP" |tee /root/build.log

make release CHROOTDIR=/home/storage/ownfreebsd BUILDNAME=FreeBSD-I4B \
CVSROOT=/home/storage/ncvs RELEASETAG=RELENG_6 MAKE_ISOS=1 \
KERNEL_FLAGS=-j4 WORLD_FLAGS=-j4 \
LOCAL_PATCHES=/root/patch.diff PATCH_FLAGS=-p1 KERNELS="I4B I4BSMP GENERIC SMP" |tee /root/build.log
</pre>

For Quick Build
<pre>
make release -DNOPORTS -DNODOC KERNELS_BASE="I4B I4BSMP GENERIC SMP" \
CHROOTDIR=/home/storage/ownfreebsd BUILDNAME=FreeBSD-I4B \
CVSROOT=/home/storage/ncvs RELEASETAG=RELENG_6 MAKE_ISOS=1 \
KERNEL_FLAGS=-j4 WORLD_FLAGS=-j4 \
LOCAL_PATCHES=/root/patch.diff PATCH_FLAGS=-p1 KERNELS="I4B I4BSMP" |tee /root/build.log
</pre>

If you want that the new generated kernel should be installed you have to edit /usr/src/release/Makefile and replace GENERIC with your kernel.

== Rebuild changes ==
<pre>
cd /usr/src/release
make rerelease -DRELEASENOUPDATE -DNOPORTS -DNODOC KERNELS_BASE="I4B I4BSMP GENERIC SMP" \
CHROOTDIR=/home/storage/ownfreebsd BUILDNAME=FreeBSD-I4B \
CVSROOT=/home/storage/ncvs RELEASETAG=RELENG_6 MAKE_ISOS=1 \
KERNEL_FLAGS=-j4 WORLD_FLAGS=-j4 \
KERNELS="I4B I4BSMP" |tee /root/build.log
</pre>

== Rebuild only the Kernels ==
<pre>
cd /usr/src/release
make release.3 CHROOTDIR=/home/storage/ownfreebsd BUILDNAME=FreeBSD-I4B \
CVSROOT=/home/storage/ncvs RELEASETAG=RELENG_6 MAKE_ISOS=1 \
LOCAL_PATCHES=/root/patch.diff PATCH_FLAGS=-p1 KERNELS="I4B I4BSMP" \
-DNOCLEAN -DNO_CLEAN | tee /root/build.log
</pre>

== Replace install.cfg ==
We replace now the install.cfg with a new version:
<pre>
cd /mnt
mkdir img
cd /usr/home/storage/ownfreebsd/R/cdrom/disc1/floppies
</pre>
