Make platform installer checklist

[r0ml]

Make a list of things to check to see if the installer works. As many as possible of these should be automated, eg using scripts + HUnit or something.

eg:

• compile hello world
• ghci -package blah
• ghc-pkg check (see for example what could go wrong)
• run full ghc testsuite perhaps
• Check all executables are .. executable
• Build canonical apps: e.g. darcs.
• Build a large subset of Hackage.
• Check that haskell platform minor versions build the same set : http://blog.well-typed.com/2009/03/regression-testing-with-hackage/

An easier way of testing building hackage: http://www.haskell.org/pipermail/cvs-ghc/2010-January/052410.html

There's the haskell-platform-test package on Hackage which hasn't been updated for a some time.
