I feel bad that I didn't suggest it before.  That's quite expected.  Subversion
was created by  CVS developers with the intention of replacing CVS.  cvs2svn
was written by the same CVS developers, who paid attention to all CVS quirks. 
cvs2svn is quite mature and it has a testsuite, if I remember correctly.

My concern is how well a Subversion repository can be mapped to git considering
that Subversion is branch agnostic.  But if it works for Mozilla, this approach
could be recommended for anything big and serious.

That's the "raison d'etre" of qgit.  I don't know if gitk has anything that qgit
doesn't, except bisecting.

Ideally, make Mozilla developers use git :-)

I think git-svn is supposed to do the svn->git part, but I'm afraid it will need
some work to do it effectively.  Google search for "cvs2svn incremental" brings
some patches.  cvsup can be used to synchronize the CVS repository.
