1.1 jason 38:
39: <p>
1.19 nick 40: Starting with 2.7, OpenBSD provides a source tree that contains
41: important patches and fixes (i.e. those from the
42: <a href="errata.html">errata</a> plus others which are obvious and simple,
43: but do not deserve an errata entry)
1.23 ! nick 44: and makes it available via <a href="anoncvs.html">CVS</a>, in addition to the
! 45: <i>-current</i> source. Thus, users can choose three options :<p>
1.4 deraadt 46: <ul>
1.19 nick 47: <li>Stick with our latest release and apply the patches by hand.
1.23 ! nick 48: <li>Use the <b>patch branch</b> which has those patches and some others
! 49: applied.
1.19 nick 50: <li>Use <b>current source</b> for all of the latest features.
1.4 deraadt 51: </ul>
52: <p>
1.19 nick 53: <!-- The <a href="plus.html">Daily Changelog</a> details (amoung other things)
54: which post-release changes have made it into the patch branch. -->
55: As a general principle, all
1.23 ! nick 56: <a href="errata.html">errata</a> entries will be merged into the patch
1.19 nick 57: branch within 48 hours of when an errata is published. Other post release
58: patches may be merged in as well, subject to a number of conditions:
1.4 deraadt 59: <ul>
1.19 nick 60: <li>The patches must be simple, short, and obviously 100% correct.
61: <li>Errata entries are made for bugs which affect many people. Other
62: patches may be merged into the patch branch if they affect a few
63: people in drastic ways.
64: <li>Please do not ask for large subsystems or patches to be merged.
65: Maintaining the patch tree takes a lot of effort which could be
66: better spent on making our next release better.
1.23 ! nick 67: <li>New or changed functionality, hardware support or APIs will
! 68: <i>not</i> be merged.
! 69: In general, if it requires a man page change, it will NOT be a
! 70: candidate for the patch branch.
1.19 nick 71: <li>As an exception to the above rules, OpenSSH release versions will be
72: merged into the patch branch.
1.4 deraadt 73: </ul>
74: <p>
1.1 jason 75:
1.23 ! nick 76: It is worth pointing out the name <i>-stable</i> refers ONLY to the API
! 77: and operations of OpenBSD not changing, not the overall reliability of
! 78: the system.
! 79: In fact, if things go as desired, the <i>-current</i>
! 80: <a href="faq/faq5.html#Flavors">flavor</a> of OpenBSD, on its way to
! 81: becoming the next <i>-release</i>, will be an improvement in
! 82: reliability, security and overall quality over the previous
! 83: <i>-release</i> and <i>-stable</i>.

1.1 jason 87:
88: <p>
1.19 nick 89: To obtain the patch branch for a particular release of OpenBSD, you
90: can update on top of a pre-existing source tree
91: (from <a href="ftp.html">FTP</a> or the <a href="orders.html">CD</a>)
92: or you can grab the source tree freshly from
93: an <a href="anoncvs.html">AnonCVS</a> server.
94: Instructions for getting the patch branch and staying up to date are
95: described in the <b>Getting Started</b> section of the
96: <a href="anoncvs.html#starting">AnonCVS documentation</a>.
97: Note that patch branches do not help to upgrade from one release of
1.21 steven 98: OpenBSD to another, e.g. to go from 3.9 to 4.0. They only provide
1.19 nick 99: a means for staying up to date with the patches within a given release.
1.23 ! nick 100:
! 101: <p>
! 102: Do not attempt to go from one release to another via source.
! 103: Instead, please visit the <a href="faq/upgrade40.html">upgrade guide</a>.
1.19 nick 104: Also, you cannot go backwards, from -current back to -stable, because of
1.23 ! nick 105: library versioning problems and other changes.

1.23 ! nick 108: <h3><font color="#0000e0">Building OpenBSD <i>-stable</i></font></h3>
! 109: Full details on building from source are provided in
! 110: <a href="faq/faq5.html">FAQ 5 - Building the System from Source</a>.
! 111: This is a simplified summary.
! 112:
! 113: <p>
1.19 nick 114: Once you have obtained a source tree via <a href="anoncvs.html">anoncvs</a>,
115: you must rebuild the system. The stages for doing so are:
1.1 jason 116:
117: <ul>
1.19 nick 118: <li>Rebuild the kernel
119: <li>Reboot with the new kernel
120: <li>Rebuild the binaries
1.1 jason 121: </ul>
122:
1.22 nick 123: <h4><font color="#0000e0">Rebuilding the kernel</font></h4>
1.1 jason 124:
125: <p>
1.19 nick 126: To rebuild the default kernel from stable:
1.22 nick 127: <blockquote><pre>
1.3 ericj 128: # <strong>cd /usr/src/sys/arch/i386/conf</strong>
129: # <strong>/usr/sbin/config GENERIC</strong>
130: # <strong>cd /usr/src/sys/arch/i386/compile/GENERIC</strong>
131: # <strong>make clean && make depend && make</strong>
1.22 nick 132: </pre></blockquote>
1.1 jason 133:
134: <p>
1.19 nick 135: Replace <i>i386</i> with your architecture, e.g.
136: <i>sparc</i>, <i>alpha</i>, etc.
1.1 jason 137:
1.22 nick 138: <h4><font color="#0000e0">Rebooting with the new kernel</font></h4>
1.1 jason 139:
140: <p>
1.19 nick 141: To reboot with the newly compiled kernel:
1.22 nick 142: <blockquote><pre>
1.3 ericj 143: # <strong>cd /usr/src/sys/arch/i386/compile/GENERIC</strong>
1.23 ! nick 144: # <strong>make install</strong> <i>(Safely install new kernel)</i>
1.3 ericj 145: # <strong>reboot</strong>
1.22 nick 146: </pre></blockquote>
1.1 jason 147:
148: <p>
1.19 nick 149: As above, substitute your architecture for <i>i386</i>. If your system has
150: trouble booting the new kernel, you can easily go back and reboot from the
1.23 ! nick 151: old kernel, now called <i>obsd</i>.
1.1 jason 152:
1.22 nick 153: <h4><font color="#0000e0">Rebuilding the binaries</font></h4>
1.1 jason 154:
1.19 nick 155: <p> To rebuild the system binaries:
1.22 nick 156: <blockquote><pre>
1.16 steven 157: # <strong>rm -rf /usr/obj/*</strong>
1.3 ericj 158: # <strong>cd /usr/src</strong>
1.16 steven 159: # <strong>make obj</strong>
160: # <strong>cd /usr/src/etc && env DESTDIR=/ make distrib-dirs</strong>
161: # <strong>cd /usr/src</strong>
162: # <strong>make build</strong>
1.22 nick 163: </pre></blockquote>
1.1 jason 164:
1.19 nick 165: <p>This will take awhile...
1.23 ! nick 166:
! 167: <p>
! 168: If you have a number of machines to keep at <i>-stable</i>, you may wish to
! 169: make a <a href="faq/faq5.html#Release">release</a>, creating the
! 170: standard install <a href="faq/faq4.html#FilesNeeded">file sets</a>,
! 171: which can then be quickly and easily installed on any machine of the
! 172: same <a href="plat.html">platform</a>.
