If I have done the following:

# mount --bind /a/b /y/z

how do I find out if /y/z has been mounted to /a/b
in a bash script?

i think it's the reverse
/a/b is now accessible as /y/z *AND* /a/b

or I'm just misreading

Maybe you could test  mount | grep /y/z  ?

Eg,
        sudo mount --bind 123 mnt
        mount | grep 123
shows
        /home/jw/tmp/123 on /home/jw/tmp/mnt type none (rw,bind)
