And it has the side-benefit of nicely handling the fairly common case of where the power comes back on just long enough to get your UPS going again, especially if it doesn't have enough power to get you through one or more whole reboot-fsck-multi-user-UPS-shutdown cycles. (It's hard to restart a whole mains power grid and it often doesn't work the first time, as another poster indicated.) Of course you could do the start-of-rc thing no matter how you handle the shutdown. And if static linking the UPS software is a problem, you might consider having it use /-based copies of their required libraries using the LD_LIBRARY_PATH env.var. or maybe (?) using (at start of /etc/rc) "/sbin/ldconfig /etc/ld-ups.so.conf".
