I have noticed that the new ...at() system calls are named in what

indicates it operates on a (directory fd, pathname) pair.
shmat operates on dirfd/pathname?
Convention collision. They unfortunately happen (yet another reason the
-at convention was ill choosen); another pretty bad clash is the f-
prefix for use on file descriptors versus use on FILE *...
