That's my understanding, too, but after some point in time, not
initially. It was explained to me some years ago after I found out
that a disk image mounted read only was modified. The trick was to
make the image '-w'.
I also have the vague feeling that once (years ago) I found a problem
when a mount failed or crashed when the image was ro.
Just a user view on this :-)
