Line 734 of my modified init of minirt.gz was missing a ';' after the test
condition. So here's where we are relative to my post #1.
1. Define a backup routine that, on command, saves a compressed copy of
/KNOPPIX-DATA in /mnt-system/KNOPPIX, as opposed to /mnt-system.
2. Redefine the init of minirt.gz to acknowledge a new cheatcode 'restore'
that is required to access the stanza which applies updates found in the
KNOPPIX directory. Only two new lines are needed.
3. Occasionaly command a backup to provide for a subsequent restore;
when needed, at start-up, include 'restore' as a cheatcode.
4. A LiveCD, although handy to have around, will not generally be required
to move the 'update' from one location to another.
Here are some loose ends for the purists:
1. Inexplicably, my minirt.gz, although now more capable in my estimation,
is actually smaller than the original. Go figure.
2. The backup program and my mods to the init of minitrt.gz are pretty ho-hum
in themselves, but there are two new cpio commands essential to this process
which I have deduced from old debian-knoppix graffiti. I hope I have applied
these correctly. I can't say I understand these details at this point.
3. In my use of this technique, I only use about half the available space
that's available. It would probably be advisable to add some code to test for
available storage before carrying out both backup and restore operations.
