If you introduce a new file onto multiple ZFS 'branches', there is no way to have it stored copy-on-write.

But copying a file from one 'branch' to another is the only way to emulate a cherrypick or merge.

So after a while of active use with many branches, you're going to have a lot of redundant copies of files all over. You're no longer making proper use of snapshots, and it becomes less efficient than having a working directory and a directory full of commits that hard link to each other.

Good point, but I bet this could be changed in ZFS.
