Unofficial cheatcode for those who miss the old official home= cheatcode

@ Professor Forester

Your observations and the avenue you have opened up here prompt me to
ask a question I could not articulate before. It is the following:

I'm happy enough working with a 2Gb SD Card which emulates a LiveUSB
rendition of Knoppix, currently 6.4.4, with lots of tweaks saved up
in knoppix-data.img. I have 1181 Mb allotted to knoppix-data.img.
I've only used about 240 Mb so far, so economizing for space is not
for me a motivator for any change.

I save my knoppix-data.img occasionally in case of a crash. But
restoring from a crash is a clumsy affair I'd like to improve upon.
A crash is defined as having shut down such that a knoppix-data-img
was written to the SDCard that now won't boot or operate properly.
Recovery for me means deleting the unworkable knoppix-data.img
and replacing it with a saved copy. Requires a CD Knoppix and time.

I'd like to re-master, without all the fuss and real estate usually
associated with it. I'd like to be able to accumulate my tweaks within
the same SD Card into past-knoppix-data.img and current-knoppix-data.img
possibly, by successively, and occasionally incorporating the
past-knoppix-data.img tweaks into the basic Knoppix compressed image
and re-allocating a diminished space for current-knoppix-data.img additions.

This, in essence, might be a mere variation of your idea.
Except here only one medium involved, the single SD Card, or USB device,
if you prefer. It may only require an option in your patch which
enables this to occur when selected by a slightly different cheatcode.

Also, FYI, my laptop thinks the SDCard slot is its USB #3 (out of 4),
and I have not found any resrictions, other than mechanical, in
treating the SD Card as any other USB device.
