Corinna -- could you _please_ re-look at supporting both
types of junctions as mount points? Then Cygwin could have
"mount-parity" with linux! ;-)
That's not easily possible. Mount points in Cygwin are virtual entries
stored in the per-user session, in-memory mount table.

Ahh.. you are making it more complicated than what I'm
asking! (yey! this should be simpler)...
If I have a junction to the root of another volume, in
cygwin it looks like a normal directory:
Using mountvol...
C:\>mountvol mountedVol \\?\Volume{578b2172-f917-11e4-b3d9-a0369f15ce28}
03/02/2017 01:24 PM <JUNCTION> mountedVol
[\??\Volume{578b2172-f917-11e4-b3d9-a0369f15ce28}\]
01/11/2017 04:17 PM <JUNCTION> var [C:\Windows\System32\cygwin\var]
### a junction is created ... under Cygwin.
Note, BTW, that 'var' is also a JUNCTION (a MS-mount point).
C:\>exit
exit

B: on /b type smbfs (binary,user,noumount,auto)
...

It's the same on linux.
linux> stat -c %D /var
822
linux> sudo mount --rbind /var/rtmp /tmp
linux> stat -c %D /tmp
822

A mount from the same fs to another place on the same fs,
looks like a normal directory (not a symlink).
This is the behavior I would want for 'JUNCTION's under
Cygwin.
On Windows, mklink creates a 'SYMLINK' or 'SYMLINKD' when
directories are linked. Those would stay as "Symlinks".
