Yes; people use @sys for a variety of things every day. There's nothing
special about binaries, you can use the same technique for anything that's
different per-platform. That's what it's for.

Believe whatever you want, but that doesn't change reality.
AFS volumes _do_ have ownership, and the owner of a volume always has the
ability to search directories and change ACL's in that volume, no matter
what you set the ACL's to.
