OK, I had this same problem with Fedora 4 and its still there with a fresh install of Fedora 5. I cant remember how I solved it last time and its driving me nuts.

Upon going through all the hassle of selecting fan speeds and temperatures for fancontrol using pwmconfig, when I select the option to save, I get the errors:

/usr/sbin/pwmconfig: line 468: tempfile: command not found
/usr/sbin/pwmconfig: Cannot create temporary file

I put the error into google and it comes up with ZERO results!

The offending line (468) in pwmconfig reads:

tmpfile=`tempfile` || {echo "$0: Cannot create temporary file" >&2; exit 1; }

I dont really know what all this means, but I tried removing the `s from `tempfile` and I upon goind through all the hassle again I get:

/usr/sbin/pwmconfig: line 470: tempfile: Permission denied
/usr/sbin/pwmconfig: line 471: tempfile: Permission denied

I give up. Help! Please! This is so annoying!

No response? Well luckily there was an option in my bios so I didnt have to use fancontrol.

Stability, multitasking, security, bugs, ease of use.. all significantly worse in linux when compared to XP in my (now quite vast) experience. Anyone who says otherwise obviously has very little knowledge of one or the other system. Had to make this rant. So annoyed with linux right now.
