I'm not out-of-the-box enthusiastic about it...

That puzzles me.  OpenSSH is upstream Cygwin-aware, and the code skips
permission checks on files if the underlying filesystem does not support
permissions (e.g. noacl or FAT FS).  What problem do you have in real
life with noacl?

I'd like to discuss this first..  But, alas, Red Tape rulez.  If you
want to provide code, you'll have to sign a copyright assignment.
Please have a look at https://cygwin.com/contrib.html.  It contains some
description and a pointer to the assignment text.


Thanks,
