On my Linux box, in bash, I have access to a "double root" folder denoted by two forward slashes:

tomas:~ $ cd /
tomas:/ $ ls
bin/ cdrom@ ...
tomas:/ $ cd //
tomas:// $ ls 
bin/ cdrom@ ...

The content of the folder and its subfolder is identical to the "normal" single slash root. The double slash does not go away when I access its subfolders. The annomaly does not repeat itself with three or more slashes; these are simple synonyms for the root:

tomas:// $ cd home/tomas
tomas://home/tomas $ cd ///
tomas:/ $ cd ////
tomas:/ $

What kindof place is it? Is it a bug? Can anyone explain the annomaly?
