Oh, so 

find /var/lib/vservers/.hash -type f -links 1 -exec rm -v '{}' ';'

does it for Debian, then. I thought I was missing something.

Below did strike as a bit much space for 253 barebone guests.

Is there a way to verify the symlinks are actually there? I don't
see them in the filesystem explicitly. Does the kernel hide it?
