The '-P' flag (prune) suppresses empty directories in the update.
Hm, okay, probably -dP is the same as -Pd. You're right, this in fact pulls in all the stuff from the entire tree. There probably should be a warning attached to this line.
You probably won't need greencard anyway, so maybe it's best to wipe it from the disk (and all the other unrelated stuff).
I have no problem with that. I think this situation is unsatisfactory, though, I'll have to cvs-update my source repository in two, maybe three separate steps, to avoid checking everything out _again_.
A safe bet is simply invoking 'cvs update' in fptools (w/o -d) and only checking for new directories if you need to. Reasoning: - If you just need one GHC from CVS, you've got a fresh checkout and only want to track minimal changes, e.g. to the STABLE branch where new directories probably won't be created (hmm, not quite true for the hierarcichal libraries now...) - You really track HEAD, in which case you know what you're doing anyway :) This is far from optimal, but hard to do any better. But as I said, that line in the building guide really ought to be fixed. Thanks for pointing this out!
