Re-mastering Proof-of-Principle Effort

[utu]

The following is a slightly abridged copy of the terminal output seen
when running the rem_10.sh command. Take note of the times for the different
phases.

So, please jump in here and help solve some of the problems (#'s 1 to 10)
or any others you've discovered.

For the un-initiated, rem_10.sh does the following:

It establishes a 15 Gb sparse-file on sdc1, works with it a while
then erases its tracks. When it's about done, it dumps a new
KNOPPIX compressed image (about 794 Mb right now)
into the KNOPPIX670 directory on sdc1.

You can verify the sparse-file by calling up a second terminal
while the first is humming away doing its job.

Mine is a 2 cpu 2.1 GHz laptop with 4 Gb ram.
The computer is 64-bits, but I'm only using 32-bit kernel, etc.
It does the 794 Mb cd renovation in about 15 minutes;
kl522 has cut that down from the 25 minutes required before the using sparse-file approach.
