Sorry about not being explicit enough. More details below.

After 'ln -s foo foo':
- 'ls foo' should perhaps show foo
- 'rm foo' should remove foo
> 2. What "incorrect" behavior are you actually seeing?
After creating foo->foo:
$ ls foo
ls: foo: Too many levels of symbolic links
$ echo $?
1
$ rm foo
rm: foo: Too many levels of symbolic links
$ echo $?
1
$ ls foo
ls: foo: Too many levels of symbolic links
I was incorrect in stating that I could not create symlinks ('ln -s foo foo').

With fusexmp:
$ ls foo
ls: foo: Too many levels of symbolic links
$ echo $?
1
$ rm foo
rm: foo: Too many levels of symbolic links
$ echo $?
1
$ ls foo
ls: foo: Too many levels of symbolic links
With MacOSX HFS+:
$ ls foo
foo
$ echo $?
0
$ rm foo
$ echo $?
0
$ ls foo
ls: foo: No such file or directory
With Linux ext3:
$ ls foo
ls: foo: Too many levels of symbolic links
$ echo $?
2
$ rm foo
$ echo $?
0
$ ls foo
ls: foo: No such file or directory
With scord (a fuse file system, similar to xmp here) on Linux ext3:
$ ls foo
ls: foo: Too many levels of symbolic links
$ echo $?
2
$ rm foo
$ echo $?
0
$ ls foo
ls: foo: No such file or directory
