	\noindent
	This chapter describes the principles and practicalities of
	building an emergency boot disk.  Such a disk is needed so
	that you can boot your system even if your hard disk (or
	at least the root partition) are unfunctional.

\section{Why is an emergency boot disk needed?}

	Many things can make your system inoperable.  In many situations,
	even though the system can't boot from your hard disk in the
	normal manner, it could boot from a floppy drive, and if you did
	that, you could perhaps fix the problem or at least save most of
	the data.
	An emergency boot disk can't save from all disasters, of course,
	but there are many small things that can go wrong that it will
	save you from.

\section{What should an emergency boot disk contain?}

A bootable kernel that is recent enough and that contains drivers for
all filesystems and hardware that you need.

Enough normal programs to be operable.  An editor is important.

Tools for making and restoring backups.

\section{Creating an emergency boot disk}

Separate boot and root disks.  Use ramdisk.

\section{Using an emergency boot disk}

Boot separately.  Mount partitions.  Do whatever is needed.
