Are you referring to this?
Assuming one large repo, the only difference between my proposal and the
book's is that there is an extra directory level in the branches (or
tags) directory for each project.  That way one doesn't have to wade
through every tag or branch name for every project.  In that sense it's
more like CVS now: tags and branches are private per module.

For example:

would most likely in an equivalent single repo setup be:

My proposal is:


That way, when you really want to see just the calc branches you can go
to /repo/branches/calc and not also see all the "paint" branches.

The one exception is for any repo-wide branches, like a GNOME release.

It could require a change in workflow, perhaps negatively.  People would
have to branch at release time, rather than delaying it until they're
ready for unstable development.  And checking into the branch and the
trunk is a PITA.  But it's probably something that warrants discussion.

But to answer the question, I'd assume that module maintainers who
branch now would simply copy their modules into the branch directory.
Perhaps it could be done by someone on the release team at release-time.

True, but any automated build tool needs to handle out-of-tree
dependencies anyway.  Reducing the maintenance for our part somewhat is
preferable to reducing it none, IMO.
