Hi Vince,

Moving the thread to the lm-sensors list, where it belongs.

That's the case of pretty much all distributions shipping lm-sensors,
as /usr/local is meant for things added on top of the original
distribution.

There's no such thing as "sensors-detect.sh" in our source package.
sensors-detect is a perl script.

If your root user doesn't have /usr/sbin in its $PATH, then your setup
is seriously broken, I doubt sensors-detect will be the only failing
tool.

sensors-detect can no longer be run as non-root, so this case doesn't
matter.

The su/sudo case is more problematic though, I can imagine a standard
user gaining root permissions without getting the $PATH usually
associated with the root user.

Can you please provide a unified diff as everyone does, so that I can
just apply it? Something like:
  diff -u sensors-detect.orig sensors-detect
should do it.

Thanks,
