Good to know.

It's not a long-term solution. In your case, since it's a new driver, it won't get overwritten. However, as mentioned in another email, the structures that are used to communicate between upsd and the drivers haven't changed much recently, and happen to be the same for the two versions you are using. If you really wanted to, you could recompile the entire .deb package.

It used to work in stock Debian. I haven't tried it myself recently - I think the only system that was up during our last power outage here was a FreeBSD system.

The system shutdown scripts should call "upsdrvctl shutdown" for you. If not, I would file a bug against the distribution package.
