Bazaar-ng and tailor

Over the last few days, I’ve done another attempt to generate a Bazaar-NG version of Samba4 using tailor. I had to fix a couple of small bugs but got it working eventually. It took me about 8 hours for 5924 revisions using the following tailor configuration:

This branch is now up on samba.org. You’ll need the bzr “newformat” branch in order to check it out.

I’m a bit disappointed by the speed of “bzr branch” (takes around 3 hours when run locally, pulling in those ~6000 revisions).

Branching from a remote branch still gives me an error (this branch is up at http://samba.org/~jelmer/bzr.samba4/ and is the same I pull from locally):
