Howdy,

I'm reading your managing software with yum document and wanted to point out that
there could be a problem with the examples that show 'su -c" some command"'. 

Su without the "-" or "- root" (e.g., "su -" or "su - root") will allow current
environment settings to be inherited by the new root shell. This could lead to
disaster if some root functions require specific settings that are NOT correct in
the previous non-root environment.

Regards,

George...
