! 30:
! 31: <p>
! 32: Starting with 2.7, the OpenBSD project is providing a source
! 33: tree that contains the patches and fixes from the
! 34: <a href="errata.html">errata</a> and making
! 35: it available via <a href="anoncvs.html">CVS</a> in addition to the
! 36: current source. Users can choose to follow either branch: current
! 37: for those who want/need all of the latest features, and the patch
! 38: branch for those who want to stick with releases and only require
! 39: the fixes and patches between releases.

! 42: <h3><font color=#0000e0>Getting a patch branch</font></h3>
! 43:
! 44: <p>
! 45: To obtain a patch branch for a particular release of OpenBSD, you
! 46: can either start with a source tree from the CD shipped with the release
! 47: of OpenBSD you want to use (see <a href="ordering.html">ordering</a>), or
! 48: you can grab the whole tree from an <a href="anoncvs">AnonCVS</a> server.
! 49: The instructions for getting a patch branch and staying up to date are
! 50: described in the Getting Started section of the
! 51: <a href="anoncvs.html#starting">AnonCVS documentation</a>.
! 52:
! 53: <p>
! 54: Please note that the patch branches are not helpful for upgrading from one
! 55: release of OpenBSD to another, eg. to go from 2.5 to 2.6. They only provide
! 56: a means for staying up to date with the patches for a given release. If
! 57: you are trying to go from one release to another via source, please visit
! 58: the <a href="faq/upgrade-minifaq.html">upgrade-minifaq</a>.

! 62: Once you have obtained a source tree via <a href="anoncvs.html">anoncvs</a>,
! 63: you must rebuild the system. The stages for doing so are:
! 64:
! 65: <ul>
! 66: <li>Rebuild the kernel
! 67: <li>Reboot with the new kernel
! 68: <li>Rebuild the binaries
! 69: </ul>
! 70:
! 71: <h4><font color=#0000e0>Rebuilding the kernel</font></h4>
! 72:
! 73: <p>
! 74: To rebuild the default kernel from stable:
! 75: <pre>
! 76: # cd /usr/src/sys/arch/i386/conf
! 77: # /usr/sbin/config GENERIC
! 78: # cd /usr/src/sys/arch/i386/compile/GENERIC
! 79: # make clean && make depend && make
! 80: </pre>
! 81:
! 82: <p>
! 83: Replace <i>i386</i> with your architecture, eg.
! 84: <i>sparc</i>, <i>alpha</i>, etc.
! 85:
! 86: <h4><font color=#0000e0>Rebooting with the new kernel</font></h4>
! 87:
! 88: <p>
! 89: To reboot with the newly compiled kernel:
! 90: <pre>
! 91: # cd /usr/src/sys/arch/i386/compile/GENERIC
! 92: # cp /bsd /bsd.old <i>(Save an old copy of your kernel)</i>
! 93: # cp bsd /bsd <i>(Copy the new kernel into place)</i>
! 94: # reboot
! 95: </pre>
! 96:
! 97: <p>
! 98: As above, substitute your architecture for <i>i386</i>. If your system has
! 99: trouble booting the new kernel, you can easily go back and reboot from the
! 100: old kernel, now called <i>bsd.old</i>.
! 101:
! 102: <h4><font color=#0000e0>Rebuilding the binaries</font></h4>
! 103:
! 104: <p> To rebuild the system binaries:
! 105: <pre>
! 106: # cd /usr/src
! 107: # rm -r /usr/obj/*
! 108: # make obj && make build
! 109: </pre>
! 110:
! 111: <p>This will take awhile...
