hdiutil attach behaviour changed with Lion

[David Katleman]

Hi Mike!

In our .dmg generation script (from Shura), we call hdiutil

hdiutil attach ./JDK7.dmg -readwrite -noverify -noidme -mountpoint $mount

In 10.6, the above command merrily ran.   Our new 10.7 (Lion) build system gives us this message

There may be a problem with this disk image.  Are you sure you want to open it?

Attach? (Y/N)

Is there something in Lion or macosx itself I need to configure to avoid this question being asked?

Seems to generate a .dmg fine if I answer "Y", but I'd like to avoid the question.

             Thanks
                         Dave
