Git mirror of a bzr tree

[Michael Terry <michael terry canonical com>]

Hello!  I'm interested in creating a (read-only) git mirror of Deja 
Dup's bzr trunk which lives on Launchpad.  This will make it easier for 
GNOME developers to play with it.

Now, bzr keeps branches in different locations (unlike git which keeps 
multiple branches in the same tree it seems).  So I assume I'd have to 
keep a 'trunk' branch that didn't change names.

Has GNOME done this before?  Is it difficult in terms of maintenance 
(i.e. would it break down and need to be poked ever)?
