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
1.2 deraadt 47: of OpenBSD you want to use (see <a href="orders.html">ordering</a>), or
48: you can grab the whole tree from an <a href="anoncvs.html">AnonCVS</a> server.
1.1 jason 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>.

61: <h3><font color=#0000e0>Building from an OpenBSD patch branch</font></h3>
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:
1.3 ! ericj 75: <ul><pre>
! 76: # <strong>cd /usr/src/sys/arch/i386/conf</strong>
! 77: # <strong>/usr/sbin/config GENERIC</strong>
! 78: # <strong>cd /usr/src/sys/arch/i386/compile/GENERIC</strong>
! 79: # <strong>make clean && make depend && make</strong>
! 80: </pre></ul>
1.1 jason 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:
1.3 ! ericj 90: <ul><pre>
! 91: # <strong>cd /usr/src/sys/arch/i386/compile/GENERIC</strong>
! 92: # <strong>cp /bsd /bsd.old</strong> <i>(Save an old copy of your kernel)</i>
! 93: # <strong>cp bsd /bsd</strong> <i>(Copy the new kernel into place)</i>
! 94: # <strong>reboot</strong>
! 95: </pre></ul>
1.1 jason 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:
1.3 ! ericj 105: <ul><pre>
! 106: # <strong>cd /usr/src</strong>
! 107: # <strong>rm -r /usr/obj/*</strong>
! 108: # <strong>make obj && make build</strong>
! 109: </pre></ul>
