62 <para>For SVN use the <filename>releng/9.1</filename> branch
63 which will be where any upcoming Security Advisories or Errata
64 Notices will be applied. The branch tag to use for updating
65 the source is <literal>RELENG_9_1</literal> for CVS.</para>

71 <para>The &man.freebsd-update.8; utility supports binary
72 upgrades of &arch.i386; and &arch.amd64; systems running
73 earlier FreeBSD releases. Systems running
74 <literal>7.[34]-RELEASE</literal>,
75 <literal>8.[12]-RELEASE</literal>,
76 <literal>9.0-RELEASE</literal>,
77 <literal>9.1-BETA1</literal>, or
78 <literal>9.1-RC[123]</literal> can upgrade as follows:</para>
80 <para>First, ensure that your current system is up to date; a
81 change was recently made to &man.freebsd-update.8; (Errata
82 Notice <link xlink:href="http://security.FreeBSD.org/advisories/FreeBSD-EN-12:01.freebsd-update.asc">FreeBSD-EN-12:01.freebsd-update</link>)
83 which is needed in order to upgrade to &os;
84 &release.current;.</para>
86 <screen>&prompt.root; freebsd-update fetch
87 &prompt.root; freebsd-update install</screen>
89 <para>Now the &man.freebsd-update.8; utility can fetch bits
90 belonging to &release.current;. During this process
91 &man.freebsd-update.8; will ask for help in merging
92 configuration files.</para>
94 <screen>&prompt.root; freebsd-update upgrade -r 9.1-RELEASE</screen>
96 <para>Due to changes in the way that &os; is packaged on the
97 release media, two complications may arise in this process if
98 upgrading from FreeBSD 7.x or 8.x:</para>
102 <para>The &os;, which previously could appear in either
103 <filename>/boot/kernel</filename> or
104 <filename>/boot/GENERIC</filename>, now only appears as
105 <filename>/boot/kernel</filename>. As a result, any
106 kernel appearing in <filename>/boot/GENERIC</filename>
107 will be deleted. Please carefully read the output printed
108 by &man.freebsd-update.8; and confirm that an updated
109 kernel will be placed into
110 <filename>/boot/kernel</filename> before proceeding beyond
115 <para>The &os; source tree in <filename>/usr/src</filename>
116 (if present) will be deleted. (Normally the
117 &man.freebsd-update.8; utility will update a source tree,
118 but in this case the changes in release packaging result
119 in the &man.freebsd-update.8; utility not recognizing that
120 the source tree from the old release and the source tree
121 from the new release correspond to the same part of
126 <screen>&prompt.root; freebsd-update install</screen>
128 <para>The system must now be rebooted with the newly installed
129 kernel before the non-kernel components are updated.</para>
131 <screen>&prompt.root; shutdown -r now</screen>
133 <para>After rebooting, &man.freebsd-update.8; needs to be run
134 again to install the new userland components:</para>
136 <screen>&prompt.root; freebsd-update install</screen>
138 <para>At this point, users of systems being upgraded from &os;
139 8.2-RELEASE or earlier will be prompted by
140 &man.freebsd-update.8; to rebuild all third-party applications
141 (e.g., ports installed from the ports tree) due to updates in
142 system libraries.</para>
144 <para>After updating installed third-party applications (and
145 again, only if &man.freebsd-update.8; printed a message
146 indicating that this was necessary), run
147 &man.freebsd-update.8; again so that it can delete the old (no
148 longer used) system libraries:</para>
150 <screen>&prompt.root; freebsd-update install</screen>
152 <para>Finally, reboot into &release.current;</para>
154 <screen>&prompt.root; shutdown -r now</screen>
