>Description:
I created an image jail using ezjail-admin with create -i option and
attempted to configure the jail by attaching it successfully.
However when I attempted to detach the image jail, ezjail-admin
showed an error and couldn't detach it.

This is caused by mounting /dev/md* directly instead of mounting
*.device symlink when ezjail-admin is invoked with config -i attach option.
>How-To-Repeat:
# ezjail-admin update
# ezjail-admin create -i -s 10m foo.example.com 192.168.0.1
# ezjail-admin config -i attach foo.example.com
# ezjail-admin config -i detach foo.example.com
Error: Jail image file foo.example.com is not attached
