Playing with git:
I have 5000 git mirror repos lying around, what happens if I put them into a single storage, all 200GB?
It gets slow. really slow. packed-refs is 50MB, the process starts requesting 50GB of virtual memory (luckily by far not all backed by actual memory), "fun"
I want to keep track of historical versions of all that stuff, while still being able to update them? Sure:
`git config set remote.origin.fetch "+refs/*:refs/heads/${timestamp}/refs/*" && git remote update`
