- POSIX does not specify mount(1) - it is inherently non-portable and 
platform specific.  So any expectation of similarity between platforms 
is bound to break (as you've discovered)

- Cygwin isn't mounting devices into the OS, but creating mappings for 
Cygwin to use. On Linux, the mount command is actually manipulating 
block devices and the kernel; on Cygwin, everything in the mount command 
is in userspace. Windows as the kernel did the actual device 
manipulation earlier on.  As such, the tool REALLY CANNOT mimic what 
Linux does, because it IS NOT doing the same things.
