	Oh, it's not _completely_ irrecoverable and is "fun" in a perverse
	way.

	First go thru all of the executable directories (/bin, /usr/bin,...)
	and identify all of the overlaid executables and save copies of them.
	Shouldn't be too many but the important one is 'ex'/'vi'.  A number
	of programs rely on using 'ex' scripts to edit generated files (the
	kernel makefiles are _good_ examples;)), and so on.  Having an older
	copy of 'ex'/'vi' is the main thing I remember as saving the day.

	Oh, I have no 2.9 systems - this was all done 10 years ago.  The
	systems I run now use MSCP/TMSCP devices and 2.9 lacks support
	for those.
