Is this what you mean?

none /cygdrive cygdrive binary,posix=0,user,noacl,override 0 0

Is this a "good thing" to do?  I find the following advice from the FAQ 
intimidating:

  Therefore, the root directory evaluated by Cygwin itself is treated as 
an immutable mount point and can't be overridden in /etc/fstab... unless 
you think you really know what you're doing. In this case, use the 
override flag in the options field in the /etc/fstab file. Since this is 
a dangerous thing to do, do so at your own risk.

Will this affect my permission-dependent stuff like ssh authentication?
