Hello guys.
The attached patch fixes several things our users complained about.
The patch introduces 3 wrappers for the service files and example
/etc/sysconfig/* configuration files
The lm_sensors-modprobe*wrapper scriptlets change the way how
the modprobe failures look like as the users had no idea that
the failures are caused by missing configuration and that
led to frequent bug reports. The wrapper checks whether the
modprobe is called with any arguments and leaves a hint
message when no modules are passed to the modprobe.
Te sensord-service-wrapper enhances the sensord service so that
it supports all relevant switches needed by the users which
were previously omitted and thus unsupported.
The service files now contain a placeholder for the target
wrapper directory and distribution build scripts can do
the substitution easily with two sed calls ...
Example for RPM based distributions:
sed -i "s|\@WRAPPER_DIR\@|%{_libexecdir}/%{name}|" sensord.service
sed -i "s|\@WRAPPER_DIR\@|%{_libexecdir}/%{name}|" lm_sensors.service
The patch is applicable on the latest trunk.
Please, check it and apply if you find it worthy.
Thank you.
Regards,
Jaromir.
