Uh, that's something I didn't look for.  I just used the word "auto"
because it sounded nice at this point.  Actually the third field
is ignored.  The important part is the "cygdrive" in the first field,
which is along the lines of, say, "proc" or "sysfs" in Linux.  We
don't have a reason (so far) to care for the FS type field in fstab.

If you mean to create permanent shared objects, that's not possible for
an admin user either without tweaking the security policy.  This policy
is by default only active for kernel mode code.
