Hi My linux box is running Redhat Fedora Core release 1. I would implement the ACL on the system, but how to compile the kernel in order to support ACL? I've been read so many documentation before send this message to you. According to the following link, it seems need to compile the custom kernel or wait for second release of Fedora in order to use ACL. Except these, could you show me how to make it work or any reference about this issus? Because the link doesn't shown anything about compile a custom kernel. http://www.redhat.com/archives/fedora-list/2003-December/msg01398.html Thanks & Thanks for your kindly attention Tony YUN
