Well, not really. We have an ugly bootstrapping script that downloads
the other dependencies:
https://github.com/haskell/cabal/blob/master/cabal-install/bootstrap.sh

Speaking of which...

Sorry, yes, the bootstrapping issue I referred to was installing
cabal-install starting from just a bare GHC installation, as you
correctly inferred. I think that script you generated is nicer than
what we do now; that would be good to have, regardless of where we
come down on the TLS situation. Is the source code that generates that
script available?
