???  If you have mount.exe + cygwin1.dll, you can write mount entries.
The mount command *creates* the registry entries.  setup.exe does
this too but this is a recent thing in the history of cygwin.  You
don't need setup.exe to prime the registry.

None of the CYGWIN.DLL setup stuff is needed.  These are leavings from
an older (pre-b20?) version of cygwin.

I think you're making things way too hard for yourself.

All that you have to do is create a .bat file with the appropriate mount
commands.  Copy cygwin1.dll + mount.exe to the system and run the .bat
command.  If both of those are already there, then you're all set.

You can even use the "mount -m" command to produce the mount commands.
That's why it was invented.

You also don't have to mount the drives on each machine, unless they're
needed for other things:

mount -s '//server/C$' /cc

would work fine.

I REALLY do not endorse mucking arond with the registry as a way to
manipulate the mount table.  There is no guarantee that the registry
format will be permanent.

Ouch.  I can see that you've put a lot of thought and effort into this
but if you are going to be making a distribution based on an older DLL,
consisting of different utilities, please set up some sort of support
channel for it.  Otherwise, we'll be seeing a lot confused people here.

And, I guarantee that just about everyone who is helping to support
people on this mailing list will be pretty unhappy about the

Thanks for the tips on setting up a shared system.
