The only way I learned was the "main guy" flipped off management and walked out. You start learning real fast. "WTF IS PXE BOOT. Session vms aren't booting. Oh jesus, JEFF! HA_ERR_KEY_NOT_FOUND people can't login ". I couldn't learn anything otherwise due to nerves, PR gating and risks of catastrophic failure. But, when I was the only person left, let's roll it. PR approved!

Same thing happened to me! Entire career is based on a guy leaving, and being forced to use history commands to learn everything. lol.
