I would not suggest using "zip" as the mechanism for backing up and
restoring.  As has been noted 10497 times in this mailing list Windows
ZIP does not properly save the bits needed to recreate things like
symlinks.

And, we've also mentioned at least as many times that you DO NOT MANIPULATE
THE REGISTRY DIRECTLY.  Use "mount -m" to create a .bat file suitable for
recreating the mount table.

So, the proper way to do this is to copy cygwin1.dll, tar.exe, mount.exe
to the other computer, in a temporary directory.  Run the .bat file
created by mount -m to recreate the mount table and use tar.exe to
extract the tar ball created.
