1.6 schwarze 843: <tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
844: This file contains everything you need except for the kernel sources,
845: which are in a separate archive.
846: To extract:
1.1 deraadt 847:
848: <blockquote><pre>
849: # <b>mkdir -p /usr/src</b>
850: # <b>cd /usr/src</b>
851: # <b>tar xvfz /tmp/src.tar.gz</b>
852: </pre></blockquote>
853:
1.6 schwarze 854: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
1.1 deraadt 855: This file contains all the kernel sources you need to rebuild kernels.
856: To extract:
857:
858: <blockquote><pre>
859: # <b>mkdir -p /usr/src/sys</b>
860: # <b>cd /usr/src</b>
861: # <b>tar xvfz /tmp/sys.tar.gz</b>
862: </pre></blockquote>
863:
864: Both of these trees are a regular CVS checkout. Using these trees it
865: is possible to get a head-start on using the anoncvs servers as
866: described <a href="anoncvs.html">here</a>.
867: Using these files
868: results in a much faster initial CVS update than you could expect from
869: a fresh checkout of the full OpenBSD source tree.

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

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