I'd rather add that to the CB revision.

But then the uncommit scenario strikes again. Back to square one.

You're right, we need some additional info. As mentioned above
that can be specified in the CB revision by differentiating the
commits created during a recursive commit from the CB and the
commits created explicitly in the NT. I don't really like the
distinction, but if it's needed for uncommit, so be it.

jam> In Aaron's spec they do, because you have:
jam> base/
jam> .bzr/
jam> branch/
jam> branches/
jam> NT1/.bzr/branch/
jam> NT2/.bzr/branch/
jam> checkout/
jam> [repository?]
jam> subdir/.bzr/
jam> branch/location => ../.bzr/branches/NT1
jam> checkout/
jam> However, as part of the spec, we want to be able to do:
jam> bzr branch http://bazaar-vcs.org/bzr/bzr.dev
jam> and have it also grab
jam> lp:bzr-svn
jam> (for example)
jam> However, I'm pretty sure Aaron is leaning towards forcing there to be
jam> local branches for all subtrees. (So even if you did 'bzr co
jam> --lightweight .../bzr.dev', you would have a local branch for bzr-svn,
jam> rather than a lightweight checkout of lp:bzr-svn.)
jam> I'm not positive to that fact though, and I don't think he has mentioned
jam> it in NestedTreeDesign yet.
I think that point is a very important one and should be clearly
defined.
