In last month the nut SuSE scripts were completely rewrote, because old
scripts were not working as they come out of factory. You can try the
latest scripts from:
http://download.opensuse.org/distribution/SL-OSS-factory/inst-source/
If you don't use SuSE Linux 10.1, you should download .src.rpm package
and recompile it for your version.

Improvements are welcome.

I am not sure, whether it is possible after quitting of upsd and
drivers.

Looking at the new package, it uses upsdrvctl shutdown with root
privileges, and it works (well, tested only with USB).

If all commands with -u argument return this error, then it is a problem
of privileges. If only powerdown returns this error, then it is a
specific problem of late halt sequence.

Well. This part is still missing in SuSE Linux 10.1. Most device things
were moved from udev to hal and we should decide, how exactly implement
it. Additionally, for serial UPS it will not help.
