1.6 schwarze 844: <tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
845: This file contains everything you need except for the kernel sources,
846: which are in a separate archive.
847: To extract:
1.1 deraadt 848:
849: <blockquote><pre>
850: # <b>mkdir -p /usr/src</b>
851: # <b>cd /usr/src</b>
852: # <b>tar xvfz /tmp/src.tar.gz</b>
853: </pre></blockquote>
854:
1.6 schwarze 855: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
1.1 deraadt 856: This file contains all the kernel sources you need to rebuild kernels.
857: To extract:
858:
859: <blockquote><pre>
860: # <b>mkdir -p /usr/src/sys</b>
861: # <b>cd /usr/src</b>
862: # <b>tar xvfz /tmp/sys.tar.gz</b>
863: </pre></blockquote>
864:
865: Both of these trees are a regular CVS checkout. Using these trees it
866: is possible to get a head-start on using the anoncvs servers as
867: described <a href="anoncvs.html">here</a>.
868: Using these files
869: results in a much faster initial CVS update than you could expect from
870: a fresh checkout of the full OpenBSD source tree.

877: A ports tree archive is also provided. To extract:

879: <blockquote><pre>
880: # <b>cd /usr</b>
881: # <b>tar xvfz /tmp/ports.tar.gz</b>
882: </pre></blockquote>
883:
884: Go read the <a href="faq/ports/index.html">ports</a> page
885: if you know nothing about ports
886: at this point. This text is not a manual of how to use ports.
887: Rather, it is a set of notes meant to kickstart the user on the
888: OpenBSD ports system.
889: <p>
1.6 schwarze 890: The <i>ports/</i> directory represents a CVS checkout of our ports.
891: As with our complete source tree, our ports tree is available via
1.1 deraadt 892: <a href="anoncvs.html">AnonCVS</a>.
893: So, in order to keep up to date with the <i>-stable</i> branch, you must make
894: the <i>ports/</i> tree available on a read-write medium and update the tree
895: with a command like:
896:
897: <blockquote><pre>
898: # <b>cd /usr/ports</b>
899: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_0</b>
900: </pre></blockquote>
901:
902: [Of course, you must replace the server name here with a nearby anoncvs
903: server.]
904: <p>
905: Note that most ports are available as packages on our mirrors. Updated
906: ports for the 6.0 release will be made available if problems arise.
907: <p>
908: If you're interested in seeing a port added, would like to help out, or just
909: would like to know more, the mailing list
910: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
