I find it interesting that you point this out, because I was just wondering wether it would be possible to just open(2) the file /usr/bin/gpg and exec(2) this file via the file descriptor from this open(2) calland not the path name. Root, of course, could still replace the /usr/bin/gpg program and get away with it, but this seems to me to guarantee that the binary can not be stolen away under the unsuspecting user's noses.
