X11 directory is duplicated under /bin

[Tecromatica]

The directory "/bin/X11" appears to be duplicated multiple directory levels deep.

For instance, I type "cd /bin/X11/X11/X11/X11/X11".

Then type the pwd command and I am six directories deep in yet another X11 directory.

/bin/X11/X11/X11/X11/X11

Since it doesn't appear to have an effect on disk space, I typed "ls -ld X11" and it shows it's a link to ".", the current directory.

output of "ls -ld X11" is:

lrwxrwxrwx 1 root root 1 Jan 29 02:30 X11 -> .

Clearly some process is creating or did create these symbolic links to the current directory.

This is likely for compatibility. /usr/bin/ is the same (/bin is a symlink to it) so there might be old software expecting /usr/bin/X11/...
