I was a new "sysmom" at SCO when this dropped. One of my senior colleagues (hey, K.!) patiently held my hand as I logged into each of our PCs running Xenix, tweaking each machines' setup before moving onto the next. Definitely more scary than the all-nighter we pulled at Netscape on New Year's Eve 2000. It felt like we were trying to prevent a contagion from spreading, which we were in fact.
