Under linux, and I would assume most variants of un*x there really isn't
a difference, whether you put a filesystem on it or not, and whether you
access it as a raw device or access a file on a mounted filesystem, you
get back out what you put in.

Maybe I expressed myself poorly.
The first use of any cygwin process will still create a '/' mount,
AFAICS that should be considered an automount, since it is
created without user intervention via the mount command.

By global configuration I meant the options
set in $CYGWIN before starting any cygnus
process.

if [no]binmode is unset use the current default of text automounts and
binary pipe/device access if binmode is set use binary automounts and
binary pipe/device access if nobinmode is set use text automounts and
text pipe/device access

Why?  if I mount -b c:/ / obviously I have my tools setup to expect
binary data, if the header/source files that I access across the network
to setup a cross compiler come from a temp // mount or an automount I
still want them to be accessed as binary, unless I specifically override
that, via a mount/remount, and I think I should be able to expect that.

As far as I'm concerned all cygwin access should be via mounted dirs,
and all of mine is, but if you aren't going to enforce that, and
are going to provide another method of disk access you should
also provide a method to set the default access mode.

defaulting to '/' mode seems to me the most logical.
