I am skeptical that this initial excitement and cloning will translate
into more developers. Also, for someone who's never used either VCS, I
think the overhead of learning to use darcs is far lower than of
learning to use git.
The move to git is more likely to help by not driving away people who
have had problems working with GHC in darcs, than by attracting
developers in the first place. New GHC developers come from GHC users,
not darcs/git users.

I'm not sure that's true. e.g. Malcolm and Ross both commit to the
bootlibs, and we get a lot of patches from various people in the

FWIW, personally I would prefer staying with darcs. I prefer its
underlying philosophy, and I find its UI far more intuitive and easy to
I don't suffer from its problems, though - but then, I don't maintain a
long-running HEAD branch, and I mostly don't use it on Windows.
However, there certainly are a number of people who are having problems
working with darcs (although in some cases this may be because they are
working in a way incompatible with darcs, e.g. one person had replaced
libraries/ with a symlink, for reasons he didn't explain).
Given darcs certainly has some problems, and I seem to be in a minority,
I don't feel I can stand in the way of a move. But I think we need a
wider discussion before we can think about moving the bootlibs to git.
If we are going to have a changeover, then the most convenient time in
GHC's development cycle to make it is in 4 or 5 weeks time.
