I fail to see the connection between filesystem and proceses being able (or not) to bind to a low port, for instance. OK, so if your httpd resides on FAT, it has no capabilities and won't work at all. Big deal. OTOH, a mount flag in the vein of suid or dev is mandatory to ensure nobody smuggles in a capable binary from elsewhere by mounting a floppy...
But AFAIKS capabilities is a systemwide decision. And even if it wasn't, binding this to the specific filesystem (or mount flags) is extra complexity, both in-kernel and for the sysadmin. Complexity precisely in the areas where you don't want any of it. No dice. -- Horst von Brand vonbrand@sleipnir.valparaiso.cl Casilla 9G, Viña del Mar, Chile +56 32 672616
