Regarding this warning in the current README:

> WARNING: If you are upgrading from an old version of cygwin, unmount
> all your old mount points and back up your old installation before
> upgrading.  YOUR OLD MOUNTS WILL BE OVERWRITTEN if you do not do this.

It doesn't apply any more, does it?  Doesn't the new setup observe
existing mounts?

Thanks,
David
