    File Permission in CentOS 5

    I am creating a DVD iso of the mentioned six .iso file using 'mkisofs' in CentOS. During the process, at about 12%, an error occurred. The error was that: "Cannot read from '/sys/firmware/acpi/namespace/ACPI/_SB/PCI0/P2P0/S4F0/eject'"
    I remembered setting all the permissions to "read and write" but I kept receiving the same error next time. Could anyone please help me to solve the problem? Thanks all.

    Generally, you do not change system file permissions. You add your user to appropriate group so you can access resources you need.
