I didn't decide, I suggested. Fernando is doing the page. If it prints a warning, it still runs, but what information is it omitting from the output? I don't know without digging, but the developer does recommend install using suid. If we do set the program suid, perhaps /bin would be better. For my system, I do have /sbin in my path as a regular user, but that's basically for development purposes. Just checking, I see /sbin/mount.nfs is suid. Also I have /usr/sbin/vmware-authd as suid, but of course that's a proprietary program that I was using to benchmark qemu against. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
