This manual describes the steps for the release and stable branches. To build a current release, additional steps may be required. See https://www.openbsd.org/faq/current.html for any needed workarounds.

Commands to be run as a user are preceded by a dollar sign ‘$’. Commands that must be run as the superuser are preceded by a hash mark ‘#’. Privileges will be de-escalated to the user build whenever possible.

Most of the defaults can be overridden by setting the appropriate variables in mk.conf(5).

1. Update sources

OPENBSD_x_y_BASE

The sources for the OpenBSD x.y release.

OPENBSD_x_y

The sources for the OpenBSD x.y stable branch. It contains the patches described in https://www.openbsd.org/stable.html.

See https://www.openbsd.org/anoncvs.html for instructions on fetching the sources for the first time.

To update existing sources to the versions identified by one of the above tags, use the commands:

$ cd /usr/src && cvs up -r TAG -Pd
$ cd /usr/xenocara && cvs up -r TAG -Pd
$ cd /usr/ports && cvs up -r TAG -Pd

Warning: cvs(1) tags are ‘sticky’. See cvs(1) for more information.

2. Build and install a new kernel

Replace GENERIC.MP with a different kernel configuration if necessary.

Create the build directory and configuration file, then compile and install the kernel:

# make obj
# make config
# make && make install

The current kernel is copied to /obsd and the new kernel to /bsd. Reboot.

3. Build a new base system

Create the tree of obj directories and begin the build:

# cd /usr/src
# make obj && make build

After the build is completed, update /etc, /var, and /dev, using sysmerge(8) and MAKEDEV(8):

# sysmerge
# cd /dev && ./MAKEDEV all

At this point, the base system is up to date with the code that will be made into a release.

4. Make and validate the base system release

Create a RELEASEDIR directory to store the release files. This directory must be writable by build.

To build a release, it is necessary to prepare a filesystem mounted with the noperm mount(8) option. Either standard FFS or mount_mfs(8) may be used. The root of this filesystem must have owner build and mode 700. On this filesystem, create a DESTDIR directory. This will be the root of a complete OpenBSD installation.

Warning: DESTDIR and RELEASEDIR must not refer to any directory with /mnt in its path, as /mnt is used in the release generation process. The vnd(4) device vnd0 is also used and must not be configured.

Make the release and check the contents of the release tarballs:

# export DESTDIR=your-destdir RELEASEDIR=your-releasedir
# cd /usr/src/etc && make release
# cd /usr/src/distrib/sets && sh checkflist
# unset RELEASEDIR DESTDIR

5. Build and install Xenocara

The following steps will build and install Xenocara.

# cd /usr/xenocara
# make bootstrap
# make obj
# make build

6. Make and validate the Xenocara release

The steps to build and validate the Xenocara release are:

# export DESTDIR=your-destdir RELEASEDIR=your-releasedir
# make release
# make checkdist
# unset RELEASEDIR DESTDIR

At this point, OpenBSD base system and X Window System tarballs are in RELEASEDIR.

7. Make the third party packages

8. Create boot and installation disk images

# export RELDIR=your-releasedir RELXDIR=your-xenocara-releasedir
# cd /usr/src/distrib/$(machine)/iso && make
# make install

The two installer images are now stored in the local release directory.
