what kind of speed up did you see with this ? are there any potential side effects ?

Hi 👍 for this!

• Concerning speed-up, it's pretty the same on little repos (but faster in case of a repo with a big history).

Without depth param.

❯ time git clone git://github.com/puppetlabs/puppet.git
Cloning into 'puppet'...
remote: Counting objects: 186943, done.
remote: Compressing objects: 100% (11/11), done.

Vs with depth param.

❯ time git clone --depth 1 git://github.com/puppetlabs/puppet.git 
Cloning into 'puppet'...
remote: Counting objects: 3530, done.

git clone --depth 1 git://github.com/puppetlabs/puppet.git  0.19s user 0.16s system 7% cpu 4.813 total

• Concerning potential side-effects, I think nothing, depth 1 fetch only the latest version so we don't have the full history in the cloned repo, but it's a fixture, not a clone used for development.

Cool. I'll get it rebased then.
