>Organization:
>Environment:

	Small machine, EG laptop in hotel, no spare hard discs, no cdrom drive,
	no ether/slip/plip network, Just the fixit floppy available, 

>Description:

	If /sbin/init is destroyed or corrupted, boot -s fails, 
	you have no spare init to copy in, you are stuck !

>How-To-Repeat:

	chmod -x /sbin/init
	boot -s	# Fail to boot off hard disc
	Boot with fixit floppy, mount your hard drives
		find / -name init -print
	chmod +x /sbin/init # to rescue yourself from the simulation
	Now think: "how could I copy in a new init if mine was damaged ?"

>Fix:
	
	Ideally, put an /sbin/init on fixit floppy, but no space:
		tunefs -m 0  /dev/rfd0c
		df /dev/rfd0c		# 72 K free
		cp /sbin/init /tmp
		gzip /tmp/init		# 109 K
	maybe there's room on the 2nd boot disc was introduced with 3.2 ?

	Or maybe we should introduce a fixit.extras floppy ?
	I suspect other files might also be needed on there ?
