"darcs record; darcs send; darcs unrecord --last=1" fails in (partial) ghc head repo

As Ian says, no, darcs doesn't work with partial repos.  The only solution we know is to start from a recent tarball (to bypass using darcs to pull the first 15000 patches), and then do darcs pull to bring it up to date.  That way you are always working on a full repo.  Sigh.
