+ <para>Short answer: You're probably at security level

+ install the kernel.</para>
+
+ <para>Long answer: FreeBSD disallows changing system flags
+ at security levels greater than 0. You can check your
+ security level with the command:</para>
+
+ <screen>&prompt.root; <userinput>sysctl kern.securelevel</userinput></screen>
+
+ <para>You cannot lower the security level; you have to boot
+ to single mode to install the kernel, or change it in
+ <filename>/etc/rc.conf</filename> then reboot. See the
+ &man.init.8 man page for details on securelevel, and
+ <filename>/etc/defaults/rc.conf</filename> for more
+ information on rc.conf.</para>
