Bug 32435

	Recently, I often saw (and answered) a specific question about
	burning CDs on -question. Users tended to burn raw files (for example
	tarballs) to CDs, and then wondered why they couldn't mount the
	CD under FreeBSD or access the data on it under a different
	operating system. Although there is a chapter about burning CDs in
	the handbook, I prepared a FAQ entry that explains how such
	"raw" CDs are to be used, and how to actually create a "real"
	ISOFS CD then can be mounted under FreeBSD and is also
	accessible under other operating systems.

Fix: Apply this diff to faq/book.sgml:

+       <para>I burned a CD under FreeBSD and now I can not read it under any other operating
+        system. Why?</para></question>
+
+        <answer>
+        <para>Most likely, you burned a raw file to your CD, probably by using a command
+         like:</para>
+
+ 	<screen>&prompt.root; <userinput>burncd -f /dev/acd1c -s 12 data archive.tar.gz fixate</userinput></screen>
+
+ 	<para>CDs are sometimes burned that way, espeically for backup purposes.
+ 	 In order to retrive the data burned to the CD in the above manner, you'd have to use
+ 	 a command like:</para>
+
+ 	 <screen>&prompt.root; <userinput>tar xzvf /dev/acd1c</userinput></screen>
+
+ 	 <para>If you want to be able to mount your CD under FreeBSD or use it under a different
+ 	  operating system, however, this method will not work. Instead, you will have to create
+ 	  an ISO 9660 filesystem from the files to be burned to your CD first. In order to do that,
+ 	  you will first have to install the <filename>sysutils/mkisofs</filename> port. Once that
+ 	  has been done, you can issue a command like:</para>
+
+ 	<screen>&prompt.root; <userinput>mkisofs --allow-lowercase --allow-multodot -r -o cdimage cddir</userinput></screen>
+
+ 	<para>This will create a file named <filename>cdimage</filename> from all files in the
+ 	<filename>cddir</filename> directory. You can then do:</para>
+
+ 	<screen>&prompt.root; <userinput>burncd -f /dev/acd1c -s 12 data cdimage fixate</userinput></screen>
+
+ 	<para>The resulting CD can be mounted under FreeBSD like any other normal CD, and it will work
+ 	 under other operating systems as well.</para>
