My IBM AS400 POS Moment
My over zealous (and unthinking) issue also involved an IBM AS400 point of sale system. I was writing a complete and critical upgrade of the security and one Monday morning a stressed looking admin asked me, as I arrived at my desk, if I had backed up my work off system. I had and he looked very relieved. It seems the admin staff had scheduled a full UNIX update that weekend. They had not mentioned this to anyone outside of their little clique. Nothing in user's space was backed up and the update involved a complete drive wipe. "Well, that takes time we don't have and we are not responsible for the backups of others." I can imagine then self-righteously declaring to themselves. There were more than a few screams in IT that day.
