Create a link to the Unix socket

Question

Is there a possibility to create a hard link for an unix socket? I'm creating a jail and symbolic links won't work, so I'm looking for a solution, how to provide an unix socket inside chrootted environment.

The only idea I'm coming across is to use something like netcat but is there any reliable possibility?

Linux at least would allow you to use a bind mount to make either a directory or alternatively a single file available at multiple places.

  # mount --bind /var/MySQL.sock /chroot/var/MySQL.sock
