It is basically not a good idea at all to cut power instead of issuing a hardware shutdown command. Lots of stuff on server boxes get highly pissed off if you just cut power. I would have to put some effort to recall all the trouble we had in the past to access whether we can support this proposed change, though. What is important is that we must not break the sane scenario, where you have the box properly configured to always power up on power restore, and the UPS configured to always cycle the load once the load (i.e. us) signals that it is past the point of no return (i.e. that it will require a power cycle to restart -- in Debian, that pretty much means as soon as we switch to runlevel 0). Also, shutdown -H must NOT issue a UPS power off command [by default], it is documented to not do it. -- "One disk to rule them all, One disk to find them.
