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 ri...@nerd.com - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - LOOK OUT!!!
