Hi all,

I've concluded my work on improving the mount system in Cygwin.
The latest (Jan 26) snapshot from the snapshot web page contains
all of the checkins.  Since you also need a matching mount.exe and
umount.exe, I've put a copy of the new winsup directory sources,
prebuilt DLL, and matching copies of mount/umount in the old
snapshot location (

If you haven't used a snapshot since Jan 15, the latest DLL will
automatically upgrade your mount tables to the new format the first
time you run a Cygwin program that uses the new DLL.  There is
also an import flag on the mount utility that forces a copy from the
old mount layout to the new one.

In short, these changes make Cygwin:

* use a new registry mount layout

* able to access and change both current user and system wide mounts
(if they have sufficient privs).

* replace the //<drive-letter>/ scheme with a system where mounts
are automatically made under the mount prefix /cygdrive.  This prefix
can be changed with the mount command as can the default flags for
automatic mounts.

Any comments are welcome, especially bug reports.
