What's New

This is a partial list of new features and systems included in OpenBSD 6.4. For a comprehensive list, see the changelog leading to 6.4.

How to install

Please refer to the following files on the mirror site for extensive details on how to install OpenBSD 6.4 on your machine:

Quick installer information for people familiar with OpenBSD, and the use of the "disklabel -E" command. If you are at all confused when installing OpenBSD, read the relevant INSTALL.* file as listed above!














How to upgrade

If you already have an OpenBSD 6.3 system, and do not want to reinstall, upgrade instructions and advice can be found in the Upgrade Guide.

Notes about the source code

src.tar.gz contains a source archive starting at /usr/src. This file contains everything you need except for the kernel sources, which are in a separate archive. To extract:
# mkdir -p /usr/src
# cd /usr/src
# tar xvfz /tmp/src.tar.gz
sys.tar.gz contains a source archive starting at /usr/src/sys. This file contains all the kernel sources you need to rebuild kernels. To extract:
# mkdir -p /usr/src/sys
# cd /usr/src
# tar xvfz /tmp/sys.tar.gz
Both of these trees are a regular CVS checkout. Using these trees it is possible to get a head-start on using the anoncvs servers as described here. Using these files results in a much faster initial CVS update than you could expect from a fresh checkout of the full OpenBSD source tree.

Ports Tree

A ports tree archive is also provided. To extract:
# cd /usr
# tar xvfz /tmp/ports.tar.gz
Go read the ports page if you know nothing about ports at this point. This text is not a manual of how to use ports. Rather, it is a set of notes meant to kickstart the user on the OpenBSD ports system.

The ports/ directory represents a CVS checkout of our ports. As with our complete source tree, our ports tree is available via AnonCVS. So, in order to keep up to date with the -stable branch, you must make the ports/ tree available on a read-write medium and update the tree with a command like:

# cd /usr/ports
# cvs -d update -Pd -rOPENBSD_6_4
[Of course, you must replace the server name here with a nearby anoncvs server.]

Note that most ports are available as packages on our mirrors. Updated ports for the 6.4 release will be made available if problems arise.

If you're interested in seeing a port added, would like to help out, or just would like to know more, the mailing list is a good place to know.
