10 Is it enough like crossdev enough to share code, with perhaps a bit of
11 abstraction? Maintaining the same thing twice is rarely a good idea...

26 Seems like people already committing cluster stuff to the sci overlay
27 could help; maybe they'll port packages, fix bugs, etc. With a new
28 overlay, we'd have to start from scratch, and I don't really see the
29 point.
