I'll also add my vote for "this should be easier." I've done it a half
a dozen times over the years and I found that the fastest method was
to take several screen shots of Cygwin setup showing what I have
installed, take those to the new machine, and manually go down the
list selecting the same things. It's stupidly low tech, but it's
actually quite fast (~ 5 minutes) and I know that it will always work
without annoying glitches.
