Ahh, having investigated further it seems the repo contains two CVS
modules which account for about 1/3 of the checkout and
are not needed (as they are standalone and separate). When I do the
final import from CVS I can skip them. Having said that I'll
need to run that over the weekend as cvsps takes up so much memory and
swaps a lot.

I tried what I think is the correct usage of git-filter-branch but I get:

ajb@pitcairn:/export/git/fresh.git$ git-filter-branch --tree-filter
'rm -rf big_dira big_dirb' dev-branch
warning: refname 'dev-branch' is ambiguous.
Which ref do you want to rewrite?


Any ideas?
