The actual implementation of link() on 10.5 allows for directory
hard links on HFS+ as long as they follow these rules:
- Source parent and destination parent cannot match
- A link is not permitted in the root directory
- Parent of 'pointed at' directory is not the root directory
- The 'pointed at' directory (source) is not an ancestor of the new
directory hard link (destination).
- No ancestor of the new directory hard link (destination) is a
directory hard link.
The man page for link(2) says (in various places):
As mandated by POSIX.1, path1 may not be a directory.
[EPERM] The file named by path1 is a directory.
STANDARDS
The link() function is expected to conform to IEEE Std
1003.1-1988 (``POSIX.1'').
But actually calling link() allows for directory hard links. Is this
an error in the documentation, an error in the function, or am I
connecting two things that shouldn't be?
