--with-pidpath=PATH

Changes the directory where NUT pid files are stored for processes running as root. By default this is /var/run. Certain programs like upsmon will leave files here.

--with-altpidpath=PATH

Programs that normally don’t have root powers, like the drivers and upsd, write their pid files here. By default this is whatever the statepath (below) is, as those programs should be able to write there.

The NUT_ALTPIDPATH environment variable overrides this at run time.

--with-statepath=PATH

Change the default location of the state sockets created by the drivers to interact with the data server upsd. Default is /var/state/ups.

The NUT_STATEPATH environment variable overrides this at run time.

--with-powerdownflag=FILEPATH

Change the default location (full filename path) of the POWERDOWNFLAG created by upsmon (as root) to tell the late-shutdown integration that this machine should tell all UPSes for which it is a "primary" NUT server to cut power to the load. Default is /etc/killpower on POSIX systems and "C:\\killpower" (note the double backslashes) on Windows.
