IC-OS Verification

To build and verify the IC-OS disk image, run:

# From
# This process requires Mac/Linux/WSL2, Git and Podman on your machine.
git clone
cd ic
git fetch origin
git checkout 8487a2be2a0a1d05843d03f07079d97ea782d440
if ./gitlab-ci/container/ -i ; then
    curl -LO
    shasum -a 256 artifacts/icos/update-img.tar.gz update-img.tar.gz
    echo "IC-OS build failed. Verification unsuccessful." >&2

The two SHA256 sums printed above from a) the downloaded CDN image and b) the locally built image,
must be identical, and must match the SHA256 from the payload of the NNS proposal.
