# in order to make cygwin properly (so that the cygwin root is the same is the C:\)
# I did these mounts (below)
# note 1: do this from dos command line, not from cygwin
#         and the example assumes cygwin is in C:\Apps\cygwin
# note 2: cygwin doesn't advice doing this, the reason being that some other applications
#         may try to add their crud into cygwin directories, causing problems
# note 3: if the first umount doesn't work, you have to umount the rootdrive by hand
#         umount -s /
#         then do the rest as shown below
