-XXX: Make we somehow more descriptive
+Mijn aanpak met 8.1-RELEASE heb ik gebruik gemaakt van wat 'vieze trucjes' die nullfs dingen en chroot.Bouwen in een jail heb ik niet
+voor elkaar gekregen omdat mdconfig i386 (32bit) niet overweg kan met een amd64 (64bit) /dev/mdctl handle. Verder kan 'stock' nanobsd.sh ook
+niet cross-builden en maakt wat vervelende aannamems van de architecture van het systeem waar het op draait.  Ik maak dus de ports en het OS in de chroot en doe de instalatie in het 'master' os.
 
-Building a FreeBSD kernel i386 called file:DEBUG on an amd64 can cause some headache:
-build# sh -c 'MACHINE_ARCH=i386 MACHINE=i386 MAKEOBJDIRPREFIX=/usr/obj/nanobsd.wleiden/i386 make KERNCONF=DEBUG NO_MODULES=yes buildkernel'
+  master# svn checkout http://svn.wirelessleiden.nl/svn/code/iris/trunk/nanobsd /root/nanobsd
+  master# mkdir -p /usr/local/jail/i386
+  master# csup -h cvsup.nl.freebsd.org /usr/share/examples/cvsup/standard-supfile
+  master# cd /usr/src
+  master# make buildworld TARGET=i386
+  master# make installworld TARGET=i386 DESTDIR=/usr/local/jail/i386
+  master# kldload nullfs
+  master# mkdir -p /usr/local/jail/i386/usr/ports ; mount_nullfs /usr/ports /usr/local/jail/i386/usr/ports
+  master# mkdir -p /usr/local/jail/i386/usr/obj ; mount_nullfs /usr/obj /usr/local/jail/i386/usr/obj
+  master# mkdir -p /usr/local/jail/i386/root/nanobsd ; mount_nullfs /root/nanobsd /usr/local/jail/i386/root/nanobsd
+  master# chroot /usr/local/jail/i386/
+  jail# setenv UNAME_m i386
+  jail# setenv UNAME_m i386
+  jail# /root/nanobsd/tools/package-build.sh
+  jail# patch -d /usr/src/sys/dev/usb -i /root/nanobsd/misc/patches/usbdevs.patch
+  jail# patch -d /usr/src/sys/dev/usb/net -i /root/nanobsd/misc/patches/if_udav.c.patch
+  jail# sh /usr/src/tools/tools/nanobsd/nanobsd.sh -c /root/nanobsd/cfg/nanobsd.wleiden
+  Info: This build will fail ones it tries to play around with memory disks.
+  jail# exit
+  master# setenv CFG_ROOT_PASSWORD `dd if=/dev/random bs=10k count=10 | tr -cd '[a-zA-Z0-9]' | cut -c -15`
+  master# echo $CFG_ROOT_PASSWORD
+  master# sh /usr/src/tools/tools/nanobsd/nanobsd.sh -c /root/nanobsd/cfg/nanobsd.wleiden
+  master# ls -alh /usr/obj/nanobsd.wleiden/_.disk.*
 
-Then install kernel CF is mounted at file:/mnt :
-# sh -c 'MACHINE_ARCH=i386 MACHINE=i386 MAKEOBJDIRPREFIX=/usr/obj/nanobsd.wleiden/i386 make KERNCONF=DEBUG NO_MODULES=yes installkernel PREFIX=/mnt'
