        <question id="kernel-chflag-failure">

          <para>I tried to install a new kernel, and the chflags failed.

	        How do I get around this?</para>

        </question>

        <answer>

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

	        greater than 0. Reboot directly to single user mode to

		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>

        </answer>
