Gitastrophe averted: Partial clones in git

After figuring out how to trim my Git repository by cutting excess branches, I suddenly had to get my laptop reimaged (I don’t know why. I just do what my IT guy tells me to). The previous instructions were for removing branches from an existing clone, but here I had a brand new laptop and wanted to clone. Of course, I could have run git clone https://path.to/my/repo followed by the steps from before, but that would entail downloading 4GB of stuff only to delete it afterwards; I was working from home that day and had little desire to wait for my home internet connection to download the equivalent of an entire movie on DVD if I didn’t absolutely have to.

Fortunately, I didn’t. I figured that git clone is little more than simply git init && git remote add && git fetch. The steps are simple:

git init my-repo
git remote add origin https://path.to/my/repo
# Now repeat the steps from last time:
git config --unset-all remote.origin.fetch
git config --add remote.origin.fetch +refs/heads/master:refs/remotes/origin/master
git config --add remote.origin.fetch +refs/heads/joeym/*:refs/remotes/origin/joeym/*
git fetch

There’s no immediate need to run git gc since no garbage was generated or downloaded.
