Instructions for locally reproducing the CI sandbox

git clone https://github.com/JuliaCI/rootfs-images.git
cd rootfs-images
julia --project -e 'import Pkg; Pkg.instantiate()'
julia --project test_rootfs.jl --treehash $ROOTFS_TREEHASH --url $ROOTFS_URL

You get the values of ROOTFS_URL and ROOTFS_TREEHASH by looking at the pipeline.yaml file.

Note: if you are looking at the CI run for a PR, you should get the ROOTFS_URL and ROOTFS_TREEHASH values from the pipeline.yaml on the PR branch (instead of the master branch).
