445: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1.1 beck 446: This file contains everything you need except for the kernel sources,
447: which are in a separate archive.
448: To extract:
449: <blockquote><pre>
1.7 bentley 450: # <kbd>mkdir -p /usr/src</kbd>
451: # <kbd>cd /usr/src</kbd>
452: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1.1 beck 453: </pre></blockquote>
1.7 bentley 454: <p>
455: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1.1 beck 456: This file contains all the kernel sources you need to rebuild kernels.
457: To extract:
458: <blockquote><pre>
1.7 bentley 459: # <kbd>mkdir -p /usr/src/sys</kbd>
460: # <kbd>cd /usr/src</kbd>
461: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>

1.1 beck 464: Both of these trees are a regular CVS checkout. Using these trees it
465: is possible to get a head-start on using the anoncvs servers as
466: described <a href="anoncvs.html">here</a>.
467: Using these files
468: results in a much faster initial CVS update than you could expect from
469: a fresh checkout of the full OpenBSD source tree.

475: <h3>Ports Tree</h3>
476: <p>
1.1 beck 477: A ports tree archive is also provided. To extract:

1.1 beck 483: Go read the <a href="faq/ports/index.html">ports</a> page
484: if you know nothing about ports
485: at this point. This text is not a manual of how to use ports.
486: Rather, it is a set of notes meant to kickstart the user on the
487: OpenBSD ports system.
488: <p>
489: The <i>ports/</i> directory represents a CVS checkout of our ports.
490: As with our complete source tree, our ports tree is available via
491: <a href="anoncvs.html">AnonCVS</a>.
492: So, in order to keep up to date with the -stable branch, you must make
493: the <i>ports/</i> tree available on a read-write medium and update the tree
494: with a command like:
495: <blockquote><pre>
1.7 bentley 496: # <kbd>cd /usr/ports</kbd>
1.15 jsg 497: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_6</kbd>
1.1 beck 498: </pre></blockquote>
1.7 bentley 499: <p>
1.1 beck 500: [Of course, you must replace the server name here with a nearby anoncvs
501: server.]
502: <p>
503: Note that most ports are available as packages on our mirrors. Updated
504: ports for the 6.6 release will be made available if problems arise.
505: <p>
506: If you're interested in seeing a port added, would like to help out, or just
507: would like to know more, the mailing list
508: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
