The nightly-build infrastructure for GHC is in disarray, and we could really do with help.  We really want
 * Continuous integration so that new test failures show up fast
 * Nightly builds on a variety of platforms, giving
   snapshots that are easy to install

Originally we used Buildbot ( Then in 2010 Ian Lynagh put a lot of work into a build-bot infrastructure, implemented in Haskell as an open-source project, GHC Builder (​  See for the reasoning at the time.

As I understand it, Builder never "caught fire", and now that Ian has moved on I don't know that anyone is maintaining it; nor are the various builders working so far as I know.  Perhaps competing technology has moved on, so that the original rationale no longer holds?  I'm not sure.

Regardless, we lack leadership in this area.  Joachim Breitner has set up Travis-CI.  (I don't know exactly what that is, but it sounds useful.)  Others have indicated interest/willingness.  But it would be fantastic to have a person, or (more plausibly) a small group who assumed leadership.

An early question would be: to continue to use a DIY system (Builder), or to move to some other better-supported (but perhaps less malleable) system.  I don't even know what the options are.

Others will be better informed than me about all this... we'd love to hear from you.

Thank you!
