That is what I had in mind for the longer term. Now that I think about it, my current patch is probably a bad way to get from here to there -- it adds a config option that would later *need* to be renamed and moved to a different category. (To be specific, the concept I have in mind is to have an option that disables the syscalls that are usually used only by libc5 and earlier.) > Thats just not an option - you would have zillions of config options. I don't see how it would be zillions, but it's possible there's something I'm not yet understanding. > Moreover this is a system call, and the system call interface is one of the few > supposed to be stable. You shouldnt simply assume that "no one will ever use sys_uselib()" - > there might be programs out there who use it. And if you have programs that need it, you (or your vendor) can set the config option accordingly. -Barry K.
