Sorry, but I don't grok that.  Why would I create a reparse point on
NTFS with this value?  This RP type would only be interesting if I can
access the information for files on a non-Windows remote filesystem to
indicate special file types.

Granted, it *could* be used by Cygwin on NTFS to indicate Cygwin's own
implementations of AF_LOCAL sockets or fifos.  Or even for symlinks.
But that would only introduce YA symlink type which would be unusable
from non-Cygwin applications.

Or am I missing something?
