Because there are quite valid reasons for "normal" programs (e.g., ld(1) and other binary-futzing tools) to do so. No, I don't want a paranoic system where I (regular user) can't do this to my own files using a random binary editor. An executable is just a normal file in Unix, can't get around this without seriously breaking lots of stuff. -- Dr. Horst H. von Brand mailto:vonbrand@inf.utfsm.cl Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
