[Nut-upsuser] Ellipse 750 USBS auto shutdown and NUT.

[Jimmy Jazz]

Hello,

is upsmon -c fsd working for you ?

I remember having a similar problem. A library wasn't found during the
halt process because /usr was on a separate partition. During the
shutdown process /usr will be dismounted before the nut stop sequence is
completed.

That could be ld-linux.so or something

look at the error message returned or run ldd /usr/sbin/upsmon to find
out which one is missing.
