Migrating OpenBSD 3.6 firewall to 4.0 on a CF card

Posted: 2007-02-04

I have an OpenBSD 3.6 machine as my home firewall. I also have a mini-itx machine with IDE-CF converter card waiting to replace it. This is the state of play

The build machine is running 4.0.


As root - lets build a chroot area in /home/chroot

cd /usr
export [email protected]:/cvs
cvs -d$CVSROOT checkout -rOPENBSD_4_0 -P src ports
cd /usr/src/sys/arch/i386/conf
config GENERIC
cd ../compile/GENERIC
make clean && make depend && make
make install
rm -rf /usr/obj/*
cd /usr/src
make obj
cd /usr/src/etc && env DESTDIR=/ make distrib-dirs
cd /usr/src
make build
cd /usr/src/etc && env DESTDIR=/home/chroot make distrib-dirs
cd /usr/src && env DESTDIR=/home/chroot make build

Update config

All wished for config should be present in the chroot


Any wished for ports files should be in the chroot

Compact flash

Transfer the required files to the CF card using flashdist http://www.nmedia.net/~chris/soekris/
