But maybe you could solve this problem more elegant and in a more compatible > way (to the old tools). Thanks for the patch (though when sending patches please use the git version since most likely a patch against previous version will not apply, which was your case. About the patch, the only possible error here is file not existing due to kernel not having support to unload modules (as you said) or /sys not mounted (that we don't care). Therefore, it would be better to change ERR to DBG instead of checking what was the error. I'm doing this now in git version.
