git - 如何重新链接 git repo 以从硬链接中受益

Question

我有几个从远程仓库克隆的工作树。如果这些是从同一个本地存储库中克隆的，我会节省大量磁盘空间，因为克隆操作会硬链接存储库文件。

是否可以从不同的来源重新克隆以生成硬链接？

我意识到我可以更改 remotes.origin.url 但这不会删除并重新链接文件。Git 也只管理部分目录，因此删除它并以这种方式重新创建它并不容易。

If space is a concern, you might even be interested in --shared flag from git clone. What would not even need hardlinks, so it would take even less space. From documentation:

When the repository to clone is on the local machine, instead of using hard links, automatically setup .git/objects/info/alternates to share the objects with the source repository. The resulting repository starts out without any object of its own.

Why is deleting and recreating and issue - why not do a clone with hardlinks or shared, then copy over the files that are not managed by git cp -R -n source target, -n for

-n, --no-clobber
do  not  overwrite  an  existing  file  (overrides a previous -i option)
