Well, what's wrong with hardcoded path to configuration file?
Just make this ./configure parameter with something meaningful (e.g. /etc/nut/)
by default and that's it. :)

Ok, I've removed nut-hal-drivers and installed plain nut, but megatec_usb
doesn't want to connect to my UPS. Seems like it can't get rid of
usbhid driver, attached to it by kernel:

By the way, in nut configs this VID/PID is mentioned as
Mustek Powermust 600USB (OMRON/87XXUPS)

And in other place we could find
#define LIEBERT_VENDORID 0x06da

which I think is either totally wrong or needs clarification, because
other UPS use this VID too.
