Mounting the boot/supp disks</A></H2> <P> <P>The RedHat boot disk <EM>boot.img</EM> is in MS-DOS format, using the <CODE>SYSLINUX</CODE> program to boot up. The supplementary disk <EM>supp.img</EM> is a Linux <CODE>ext2</CODE> filesystem. If you have support for the loopback filesystem in your Linux kernel, you can mount both of these files in your filesystem and hack at them: <P> <P> <BLOCKQUOTE><CODE> <PRE> # mkdir -p /mnt/boot /mnt/supp # mount -o loop -t msdos boot.img /mnt/boot # mount -o loop supp.img /mnt/supp </PRE> </CODE></BLOCKQUOTE> <P> <P>Now you should be able to see and manipulate the files on the boot and supplementary disk under <EM>/mnt/boot</EM> and <EM>/mnt/supp</EM> respectively. Phew! Note that older versions of <CODE>mount</CODE> may not be able to handle the <CODE>-o loop</CODE> option. In these cases you'll need to explicitly use <CODE>losetup</CODE> to configure the loopback device for each file, e.g. <P> <P> <BLOCKQUOTE><CODE> <PRE> # losetup /dev/loop0 boot.img # mount -t msdos /dev/loop0 /mnt/boot </PRE> </CODE></BLOCKQUOTE> <P> <P>You might also need to explicitly use the <CODE>-t ext2</CODE> option when mounting an <CODE>ext2</CODE> filesystem like the one on the supplementary disk. But, it looks like people with modern Linux distributions shouldn't have to worry about this. <P> <P>Of course, if you don't want to mess around too much, you can cut a corner and manipulate actual floppy disks rather than these floppy disk images. If time is important, you'll probably prefer to use the loopback devices, since you can hack around with the disk images without incurring the latency associated with a genuine floppy disk read/write. <P> <P> <P> <HR> <A HREF="KickStart-HOWTO-9.html">Next</A> <A HREF="KickStart-HOWTO-7.html">Previous</A> <A HREF="KickStart-HOWTO.html#toc8">Contents</A> </BODY> </HTML>
