something like this should still work, though (untested):

1)
On the reference system:

  mount -m > mounts.bat
  cd /
  tar -cjf /cygdrive/c/cygwin.tar.bz2 --exclude=/etc/passwd --exclude=/etc/group

2)
"Somehow" copy the following files to a temp directory on the new system, e.g.,
c:\tmp:

cygwin1.dll
mount.exe
mkpasswd.exe
mkgroup.exe
tar.exe
bzip2.exe
mounts.bat
cygwin.tar.bz2

3)
In c:\tmp

  .\mounts.bat
  mkpasswd -l # or -d, or whatever options are appropriate
  mkgroup -l  # or -d, or whatever options are appropriate
  c:
  cd \cygwin # or whereever cygwin's root is
  tar --use-compress-program=/cygdrive/c/tmp/bzip2.exe -xf /cygdrive/c/tmp/cygwin.tar.bz2

There are probably some details that I forgot and some other minor
cleanups to worry about but I don't see why the above shouldn't
work, at least in principle.
