Unfortunately "mkisofs" failed because /proc/kcore exceeded its 4GB file size limit. In fact, the size of the kcore on my system is shown to be 128TB, and the machine itself only contains 2GB of RAM. Has anyone experienced the same problem? BTW, the kcore files on my redhat machines reflect the actual RAM size as it should be. Also, does anyone know why "mkisofs" even tries to copy a virtual file into the ISO image it is creating? All 64-bit systems show 128TB of kcore, as that's the limit the 64-bit chipset can handle and kcore is set up to map the maximum memory. If you're imaging your system for a DVD or whatever, you shouldn't image any of the virtual filesystems (/proc or /sys) or any hardware devices (/dev) in the first place. Use something like: genisoimage -m "/proc/*" -m "/sys/*" -m "/dev/*" -m core ... ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, C2 Hosting ricks@xxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - LOOK OUT!!!
