894: This file contains everything you need except for the kernel sources,

896: To extract:
897:
898: <blockquote><pre>
899: # <b>mkdir -p /usr/src</b>
900: # <b>cd /usr/src</b>
901: # <b>tar xvfz /tmp/src.tar.gz</b>
902: </pre></blockquote>
903:
904: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
905: This file contains all the kernel sources you need to rebuild kernels.
906: To extract:
907:
908: <blockquote><pre>
909: # <b>mkdir -p /usr/src/sys</b>

914: Both of these trees are a regular CVS checkout. Using these trees it
915: is possible to get a head-start on using the anoncvs servers as
916: described <a href="anoncvs.html">here</a>.

933: Go read the <a href="faq/ports/index.html">ports</a> page
934: if you know nothing about ports
935: at this point. This text is not a manual of how to use ports.
936: Rather, it is a set of notes meant to kickstart the user on the
937: OpenBSD ports system.
938: <p>
939: The <i>ports/</i> directory represents a CVS checkout of our ports.
940: As with our complete source tree, our ports tree is available via
941: <a href="anoncvs.html">AnonCVS</a>.
942: So, in order to keep up to date with the -stable branch, you must make
943: the <i>ports/</i> tree available on a read-write medium and update the tree
944: with a command like:
945:
946: <blockquote><pre>
947: # <b>cd /usr/ports</b>
948: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_4</b>
949: </pre></blockquote>
950:
951: [Of course, you must replace the server name here with a nearby anoncvs
952: server.]
953: <p>
954: Note that most ports are available as packages on our mirrors. Updated
955: ports for the 6.4 release will be made available if problems arise.
956: <p>
957: If you're interested in seeing a port added, would like to help out, or just
958: would like to know more, the mailing list
959: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
