And, I always looked like the hero when I got someone's photos or important business data off to a USB key or similar.
As others have pointed out, not a surprise I ended up in DevOps/SRE given the above.
GO FUND KLAUS.
PLEASE.
Super nostalgic for me just to see the name. My computing teacher gave me a Knoppix LiveCD when I was about 18 and I immediately fell in love with Linux. Within weeks I was (repeatedly) attempting to install Gentoo on my first computer that I built. What a wonderful project!
I used knoppix (and later SLAX) in high school to reboot shared computers (library, labs, etc) and then extract the SAM file from the C:\ drive. I would shuttle the file home on a USB stick and crack it overnight. After doing this on a handful of computers I ended up having virtually every teacher/admin password in the school, including the domain admin which was no shit all lowercase "north". The crack was so fast f…
I ended up scraping a whole bunch of credentials, even teacher creds, but they were always permissioned. Math teacher had a single folder where math stuff was dumped but couldn't escape that.
One day we were sitting in one of the computer labs, and written on the board was just:
U: training P: training
with no effort having been made to erase it.
That turned out to be effectively complete teacher level access. They couldn't decide what to do with a bunch of student teachers so just gave them unnamed creds with access to all subjects. And they left the account active for 12 months after the training program. By then, we had scavved up the credentials of a teacher who had been at the school since its inception, and thus had done every job and had the same sort of teacher god rights. His password was just redrocket or something silly.
I had exams, exam answers, notes on student performance, basically everything possible for 3 years. I am so glad there was no logging or anything sensible or I would have been expelled too.
When someone on my team started playing with this new Knoppix thing I was blown away: not just a rescue disk but a full-on distribution!
Moral: publish your hacks!
Hey, I found the email:

Hello Mr. Russel,
I'm trying to use your compressed loopback device as found on the LinuxCare rescue CD-Rom, for my selfconfiguring Linux distribution that runs entirely from CD (including XFree and KDE).
Unfortunately, the version that I got of the cloop device seems to act quite instable (of course I recompiled it for Kernel 2.2.15, which should not differ all too much from 2.2.14). I blame it on the fact that the file handle is being read from stdin of insmod, but it could be something different.
With an SMP-Kernel, cloop.o crashes immediately on insmod when calling fget(0). With a non-SMP kernel, it kills the kernel block buffer system, shutting down all other block devices as well, when accessing certain large files on an ext2 filesystem within the compressed block device file. It seems that the ll_rw_block() routine fails in that case, and wait_for_buffer() never returns, locking up something in the kernel block buffer management.
Do you maybe have a newer version of cloop that I can start working on? Btw, I found and fixed the bug in extract_compressed_fs.c, but I think it would really be nice if the sources for the whole package could be downloaded from LinuxCare somewhere without having to get the whole CD-Rom image.
If I find the cloop lockup-bug before you have time to answer, I will send a patch.
