1checkout.defaultRemote:: 2 When you run 'git checkout <something>' 3 or 'git switch <something>' and only have one 4 remote, it may implicitly fall back on checking out and 5 tracking e.g. 'origin/<something>'. This stops working as soon 6 as you have more than one remote with a '<something>' 7 reference. This setting allows for setting the name of a 8 preferred remote that should always win when it comes to 9 disambiguation. The typical use-case is to set this to 10 `origin`. 11+ 12Currently this is used by linkgit:git-switch[1] and 13linkgit:git-checkout[1] when 'git checkout <something>' 14or 'git switch <something>' 15will checkout the '<something>' branch on another remote, 16and by linkgit:git-worktree[1] when 'git worktree add' refers to a 17remote branch. This setting might be used for other checkout-like 18commands or functionality in the future. 19 20checkout.optimizeNewBranch:: 21 Optimizes the performance of "git checkout -b <new_branch>" when 22 using sparse-checkout. When set to true, git will not update the 23 repo based on the current sparse-checkout settings. This means it 24 will not update the skip-worktree bit in the index nor add/remove 25 files in the working directory to reflect the current sparse checkout 26 settings nor will it show the local changes.
