Gee, I haven't seen this discussed for months/years.  The reason that it
appears you can't umount / is simple.  The initialization of the Cygwin1.dll
will create the / directory mount if it doesn't exist.  You actually do remove
the entry for / with the umount; however, when you do mount to check to see if
it's gone it gets added back during the initialization.  This has been resolved
by today's version of mount which uses a -f switch to replace the existing
entry.  I.E.: mount -f -b c:/ / would add make c:/ the root with binary mode
processing as the default.
