The builder is a restricted environment used by FreeSBIE developers/users to build a FreeSBIE ISO image using one of the availiable buildsets.

1. Check out the builder and the buildsets cvs module on cvs.freesbie.org (Hint: checkout builder first, enter the builder directory and check buildsets out inside the builder directory)
2. From the builder directory, as root, launch: env BUILDSET=builder BASEDIR=”/usr/local/builder” ./freesbiemake installworld, where /usr/local/builder is the location where you want to install your builder environment to.
3. Prepare the restricted environment as follows:
   1. mount_devfs devfs /usr/local/builder/dev
   2. mount_nullfs $LOCATION_OF_BUILDER_BUILDSET_AND_FREESBIE_CHECKOUTS /usr/local/builder/root
   3. cp /etc/resolv.conf /usr/local/builder/etc/resolv.conf
   4. kldload g_md
   5. kldload linux
4. Log in the builder environment: chroot /usr/local/builder /bin/tcsh
5. Bootstrap the builder environment, installing the mandatory tools: /root/builder/bootstrap
6. You’re now ready. You can build the buildset you wish, using /root/builder/completerun $YOURBUILDSET
