# new bind mount
/mnt/server-share/some/other/directory /mnt/task2 none binary,bind

Which tries to mount to 

%CYGWIN_ROOT%/mnt/server-share/some/other/directory

when I do a 'mount -a' in the same session.  If I instead put in

//server/some/directory/some/other/directory none binary 0 0

then everything works OK, AFAICS.  This might be related to the fact that
some bind mounts appear before the physical mounts in the mount table (not
in fstab!), at least if the mounts are processed in the same order.


Regards,
Achim.
