1.1 jason 39:
40: <p>
1.19 nick 41: Starting with 2.7, OpenBSD provides a source tree that contains
42: important patches and fixes (i.e. those from the
43: <a href="errata.html">errata</a> plus others which are obvious and simple,
44: but do not deserve an errata entry)
1.23 nick 45: and makes it available via <a href="anoncvs.html">CVS</a>, in addition to the
46: <i>-current</i> source. Thus, users can choose three options :<p>
1.4 deraadt 47: <ul>
1.19 nick 48: <li>Stick with our latest release and apply the patches by hand.
1.23 nick 49: <li>Use the <b>patch branch</b> which has those patches and some others
50: applied.
1.19 nick 51: <li>Use <b>current source</b> for all of the latest features.
1.4 deraadt 52: </ul>
53: <p>
1.19 nick 54: <!-- The <a href="plus.html">Daily Changelog</a> details (amoung other things)
55: which post-release changes have made it into the patch branch. -->
56: As a general principle, all
1.23 nick 57: <a href="errata.html">errata</a> entries will be merged into the patch
1.19 nick 58: branch within 48 hours of when an errata is published. Other post release
59: patches may be merged in as well, subject to a number of conditions:
1.4 deraadt 60: <ul>
1.19 nick 61: <li>The patches must be simple, short, and obviously 100% correct.
62: <li>Errata entries are made for bugs which affect many people. Other
63: patches may be merged into the patch branch if they affect a few
64: people in drastic ways.
65: <li>Please do not ask for large subsystems or patches to be merged.
66: Maintaining the patch tree takes a lot of effort which could be
67: better spent on making our next release better.
1.23 nick 68: <li>New or changed functionality, hardware support or APIs will
69: <i>not</i> be merged.
70: In general, if it requires a man page change, it will NOT be a
71: candidate for the patch branch.
1.19 nick 72: <li>As an exception to the above rules, OpenSSH release versions will be
73: merged into the patch branch.
1.4 deraadt 74: </ul>
75: <p>
1.1 jason 76:
1.23 nick 77: It is worth pointing out the name <i>-stable</i> refers ONLY to the API
78: and operations of OpenBSD not changing, not the overall reliability of
79: the system.
80: In fact, if things go as desired, the <i>-current</i>
81: <a href="faq/faq5.html#Flavors">flavor</a> of OpenBSD, on its way to
82: becoming the next <i>-release</i>, will be an improvement in
83: reliability, security and overall quality over the previous
84: <i>-release</i> and <i>-stable</i>.

1.23 nick 87: <h3><font color="#0000e0">Getting <i>-stable</i> source code</font></h3>
1.1 jason 88:
89: <p>
1.19 nick 90: To obtain the patch branch for a particular release of OpenBSD, you
91: can update on top of a pre-existing source tree
92: (from <a href="ftp.html">FTP</a> or the <a href="orders.html">CD</a>)
93: or you can grab the source tree freshly from
94: an <a href="anoncvs.html">AnonCVS</a> server.
95: Instructions for getting the patch branch and staying up to date are
96: described in the <b>Getting Started</b> section of the
97: <a href="anoncvs.html#starting">AnonCVS documentation</a>.
98: Note that patch branches do not help to upgrade from one release of
1.21 steven 99: OpenBSD to another, e.g. to go from 3.9 to 4.0. They only provide
1.19 nick 100: a means for staying up to date with the patches within a given release.
1.23 nick 101:
102: <p>
103: Do not attempt to go from one release to another via source.
104: Instead, please visit the <a href="faq/upgrade40.html">upgrade guide</a>.
1.19 nick 105: Also, you cannot go backwards, from -current back to -stable, because of
1.23 nick 106: library versioning problems and other changes.
1.1 jason 107:
108: <a name="building"></a>
1.23 nick 109: <h3><font color="#0000e0">Building OpenBSD <i>-stable</i></font></h3>
110: Full details on building from source are provided in
111: <a href="faq/faq5.html">FAQ 5 - Building the System from Source</a>.
112: This is a simplified summary.
113:
114: <p>
1.19 nick 115: Once you have obtained a source tree via <a href="anoncvs.html">anoncvs</a>,
116: you must rebuild the system. The stages for doing so are:
1.1 jason 117:
118: <ul>
1.19 nick 119: <li>Rebuild the kernel
120: <li>Reboot with the new kernel
121: <li>Rebuild the binaries
1.1 jason 122: </ul>
123:
1.22 nick 124: <h4><font color="#0000e0">Rebuilding the kernel</font></h4>
1.1 jason 125:
126: <p>
1.19 nick 127: To rebuild the default kernel from stable:
1.22 nick 128: <blockquote><pre>
1.3 ericj 129: # <strong>cd /usr/src/sys/arch/i386/conf</strong>
130: # <strong>/usr/sbin/config GENERIC</strong>
131: # <strong>cd /usr/src/sys/arch/i386/compile/GENERIC</strong>
132: # <strong>make clean && make depend && make</strong>
1.22 nick 133: </pre></blockquote>
1.1 jason 134:
135: <p>
1.19 nick 136: Replace <i>i386</i> with your architecture, e.g.
137: <i>sparc</i>, <i>alpha</i>, etc.
1.1 jason 138:
1.22 nick 139: <h4><font color="#0000e0">Rebooting with the new kernel</font></h4>
1.1 jason 140:
141: <p>
1.19 nick 142: To reboot with the newly compiled kernel:
1.22 nick 143: <blockquote><pre>
1.3 ericj 144: # <strong>cd /usr/src/sys/arch/i386/compile/GENERIC</strong>
1.23 nick 145: # <strong>make install</strong> <i>(Safely install new kernel)</i>
1.3 ericj 146: # <strong>reboot</strong>
1.22 nick 147: </pre></blockquote>
1.1 jason 148:
149: <p>
1.19 nick 150: As above, substitute your architecture for <i>i386</i>. If your system has
151: trouble booting the new kernel, you can easily go back and reboot from the
1.23 nick 152: old kernel, now called <i>obsd</i>.
1.1 jason 153:
1.22 nick 154: <h4><font color="#0000e0">Rebuilding the binaries</font></h4>
1.1 jason 155:
1.19 nick 156: <p> To rebuild the system binaries:
1.22 nick 157: <blockquote><pre>
1.16 steven 158: # <strong>rm -rf /usr/obj/*</strong>
1.3 ericj 159: # <strong>cd /usr/src</strong>
1.16 steven 160: # <strong>make obj</strong>
161: # <strong>cd /usr/src/etc && env DESTDIR=/ make distrib-dirs</strong>
162: # <strong>cd /usr/src</strong>
163: # <strong>make build</strong>
1.22 nick 164: </pre></blockquote>
1.1 jason 165:
1.19 nick 166: <p>This will take awhile...
1.23 nick 167:
168: <p>
169: If you have a number of machines to keep at <i>-stable</i>, you may wish to
170: make a <a href="faq/faq5.html#Release">release</a>, creating the
171: standard install <a href="faq/faq4.html#FilesNeeded">file sets</a>,
172: which can then be quickly and easily installed on any machine of the
173: same <a href="plat.html">platform</a>.
