What Angela said.

To explain that error above, /proc is special.  It is not a normal filesystem 
in which you can create files.  It's a filesystem-like window into the kernel. 
 The kernel creates files there and makes it appear as though they contain 
information, even though they really don't.

This explains some oddities about the stuff in /proc, like all the zero-length 
files which when you cat them give you stuff.
