I suspect for 99.9% of the users who would use this option, it will work just fine, as they only have 1 user on the system at a time. So, if you have multiple users on the physical system, then don't use $local :) Feel free to send a update to the documentation that illustrates this limitation of the feature. thanks, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
