Hi
Nowm it works
a) As written, I added nut as additional package to buildroot
b) I added the configfiles of to the rootfs.tar archive in outgoing/images
c) as nut runs as user "nobdoy" I needed to give the usb devices/serial devices
to which the UPSes are connected, rw permission for everybofy
d) I then build the image for the board.
e) upsdrcctl can be started using no special option. upsd needs to be started
with option -4 as DNS resolution would not work otherwise at least for my
board (upsd is connectiing to localhost)
f) using upsc, I can query the status of the connected upses

That's great Tilman!
It seems like a natural for a high reliability embedded system.
I know from the archlinux build here that you can specify the username and
group, that nut will run as, at configure time:
--with-user=nut --with-group=nut
Then you would have to create the nut user (and group) and assign the
permissions to it.
This would keep you from having to give the user nobody access rights to the
hardware.
Building as part of buildroot makes it nicely integrated.
