Let's see what procfs reports: [root@arch ~]# ls -l /proc/$$/exe lrwxrwxrwx 1 root root 0 Jul 23 19:58 /proc/884/exe -> /bin/bash Doesn't seem quite right....
That's because it looks like a symlink, it feels like a symlink, but it's not really a symlink.
So, from my point of view it looks like procfs is the one who has got it wrong. We should probably fix that (IMVHO).
If you remove a running process's executable, that "symlink" will now read "$filename (deleted)".
Surprisingly, you will be able to open(2) this alleged "symlink".
