OpenBSD Tools

Purpose

Contained in this repository are various scripts, config files, and other handy code I have generated over the years of running OpenBSD (mostly as a firewall/router/jack-of-all-trades server) for my home network.

Included Tools

build-openbsd.py

This is a wrapper for building the OpenBSD source code, both kernel and userland binaries.

It also includes functionality to checkout and update a CVS respository.

Dependencies

• Python (at least 2.7 due to use of argparse)
• Enough disk space to checkout source from CVS and build binaries. (comp${release}.tgz)

Operation

These commands are all expected to be run as root, our via Sudo.

build-release.sh

This shell script just collects the commands for creating a release of OpenBSD.

It expects a fully built kernel and userland in /usr/src

Operation

Simply run 'build-release.sh'

The directory used for collecting the necessary files is /usr/build/dest, the destination directory.

The directory that will be the final destination for installation files is /usr/build/rel, the release directory.

The release directory is what should be published to your local FTP or HTTP server for access by install clients.
