File Permission


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.

Ok, totally guessing here on some of this. That file is a sysfs file. My guess is that it is not there. I would check the parent directory to see if a file named eject is present.

If not, create one, and you may need to add a value inside of 0 or 1.
