Per the POSIX definition, symlinks, directories, FIFOS, and all other
special files are still "files" - the term "file" includes not only
"regular files" but all other named entities in the file system.
Directories are the only special file type that cannot generally be
hardlinked according to POSIX rules (and even then, POSIX allows the
Solaris behavior where the superuser CAN hardlink directories, with the
caveat that doing so causes weird behaviors).
