INSUBCONTINENT EXCLUSIVE:
This pilot fish builds a lot of Linux systems that have to be compliant with U.S
Department of Defense/Defense Information Systems Agency STIG security requirements, but he tries to lessen the pain by assigning root
passwords that are secure but easily remembered
Naturally, he sends them to the owner via encrypted email.When the Nvidia driver in one of those machines gets corrupted after the system
goes down hard in a power outage, fish needs root access to reinstall the driver
Unfortunately, the user of that machine (who, just incidentally, had ignored the warnings about that plannedpower outage) has no
recollection of the root password, and he can&t get it from his email
Why? He has uninstalled all his old encryption certs, so older encrypted emails can no longer be decrypted.
