Why does VCS based bug tracking software always use its own branch?

I know this may seem like a silly and tiny issue, but I can't understand why they do this (take for example tic-git (https://github.com/schacon/ticgit) which appears to be quite popular). Surely it would be better to place the data in a folder and have it in every branch, so modifications to the bug database can persist across branches and merges, and 开发者_如何学Pythonbug fixes can be tied to the commit which resolved them?

Yes, that's the other approach, which Bugs Everywhere uses. There's an old LWN article that does a survey of Distributed Bug Trackers as of a few years ago that may be of interest.

By keeping bugs in a separate branch they avoid merging bugs.
