The only way that could go wrong is, if the user already has 30 mount
points, since that's the current maximum nuber of allowed mounts.

No, but I don't think it would hurt to enhance setup.exe, either by
adding arguments to postinstall/preremove scripts, or by adding an
environment variable like $CYGWIN_AUDIENCE with the values "all_user" or
"just_me".
