See the rationale in the patch -- any iBCS application will need a significant kernel patch. If people add this kernel patch they can easily patch the three more places that detect the executables. But it does not make sense for all Linux kernels to always check for iBCS executables when they don't have to code to run them anyways. Now if iBCS support is truly as important as you claim I'm sure someone will eventually submit a patch for mainline to support it properly. If yes the hooks can be readded in a clean way, not in a hackish way like they currently exists. -Andi >
