So what technical obstacles are there preventing fossil from adopting this behavior? One idea: all blobs could be sync'd but blobs would need to be blessed before becoming part of the official fossil record. Various mechanisms might exist for such blessing. The anti-fork mechanism: before a node is blessed it would need to prove that the node it was derived from had no children unless the branch name was different. Anyone trying to push a non-blessed blob would get a big fat warning and the onus would be on them to resolve at their end before trying to sync again. > > If you have permission to force a non-fast-forward push then you can > replace/overwrite the current branch "tip/HEAD" pointer.
