There's at least one really difficult thing: how do you merge two projects using two different hash functions? The Git repository, for example, has several (I don't remember how many) root repository, and was originally made of several projects (git, gitk, git gui, ...). If these projects had started using different hash functions, then, either: * Git would have needed to learn how to merge, and record the merge history, of projects using different hash functions. * One of the projects would have been forced to be converted to another hash function, which means changing all its identifiers (so, for example, finding a message on gmane telling that commit 1ab23cde fixes your problem wouldn't help much anymore ...). -- Matthieu -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
