I worked at a solar SCADA company that rolled there own APT packages.

In the pre and post install deb package scripts there was all kinds of crazy shit, like upgrading grub to grub 2 and manually messing with boot sectors. All this stuff in packages innocuously named modbus_driver.deb or what have you, and all in absolutely the most archaic bash syntax possible.

Eventually somebody mixed a rm -rf /bin/* with rm -rf / bin/*, and the rest is history. They bricked about 100 embedded PC's, all in remote locations, all powering powerplant SCADA systems that did stuff like connect to CalISO for grid management or collect billing information. It cost hundreds of thousand of dollars to fix.
