Generating OpenBSD images using resflash.

Preparing an OpenBSD system to create the resflash images

• Install the a OpenBSD system using the architecture you would like to be the image for.

• To have sufficient space for the tlaloc/resflash scripts to build the image on the hard drive as root we are redirecting the roots home directory.

su
cp -Rp /root /home/
mv /root /root.bak
ln -s /home/root /root

IMPORTANT: It is recommended to have at least 50 GB free disk space to build the image.

Building the resflash image and file system files

• Download the tlaloc project repository, change to the project directory and start the default build.

cd ~
git clone https://github.com/xoro/tlaloc.git
cd tlaloc
./tlaloc.sh

The created image and file system files can be found in the image directory within the tlaloc project directory.

Putting the image on a hard diskflashimg.amd64-date

• The simples way to put the image onto a hard disk is using the dd command on UNIX systems.

  • OpenBSD:

    dd if=resflash-amd64-com0-115200-20150720_0257.img of=/dev/rsd3c bs=1m
    

  • FreeBSD:

    dd if=resflash-amd64-com0-115200-20150720_0257.img of=/dev/ada1 bs=1m
    

  • Mac OSX:

    dd if=resflash-amd64-com0-115200-20150720_0257.img of=/dev/disk1 bs=1m
    

  • Linux:

    dd if=resflash-amd64-com0-115200-20150720_0257.img of=/dev/sda0 bs=1M
    

Converting the resflash image to a Virtualbox vdi image file

• Copy the resflash image to system that contains an installed version of Virtualbox and execute the following statement on the command line:

VBoxManage convertfromraw resflash-amd64-com0-115200-20150720_0257.img resflash-amd64-com0-115200-20150720_0257.vdi --format vdi

Starting the reflash image im qemu

It is possible start the resflash build image in qemu under OpenBSD. Therefore you have to install qemu on Openbsd using the following command:

pkg_add qemu

Then you can start the reflash image from within the tlaloc directory using this command:

qemu-system-x86_64 -nographic resflash-amd64-com0-115200-20150720_0257.img

If you created the resflash image using a different architecture than x86_64 just use the appropriate qemu-* executable.
