Leave it alone. > Fine, but I still plan on sending you the update to give all files unique inode numbers. If it screws up tar, it could possibly screw up something else.

You have a point that this would just fix this release and the older kernels would still be broken, but the identical inode numbers is something I don't want to later find out breaks something. -- Steve
