Nautilus: How to add/remove filesystems from appearing in "Removable Media" and Desktop?

[Daniel B. Thurman]

I would like to prevent certain filesystems from automatically
appearing in the "Removable Media" panes and from appearing
on the user's desktop as icons.

Is there also a way to control what filesystems appear on a per
user basis as well?

I have both F9 and F11 and certainly the behavior is different
between these OSes but nonetheless, I would like to manage
these behaviors as much as possible.

I looked on the Internet and also locally on my systems
via menus and so on but have not been successful finding
out what I need.

Thanks!
Dan
