root/lm-sensors/branches/lm-sensors-2.10/Makefile

Revision 5762, 16.3 KB (checked in by khali, 3 years ago)

Recent versions of module-init-tools only want *.conf files under
/etc/modprobe.d. So rename our configuration file to lm_sensors.conf
there. Also let "make install" rename the file if it already exists.
