Nice! Just a note for the future: some ulimit command in our setup_commands can possibly be moved to cloud-init time as well? E.g., https://github.com/lework/kainstall/blob/7a59178afe187f05cc4d78ce63947589f69fc9bd/kainstall-ubuntu.sh#L351-L376

Great point! We should do that, that can also help us get rid of many prlimit commands for ray. Filed an issue #1957

The previous way to disable the unattended-upgrade significantly increase the provisioning time of AWS cluster, due to the apt remove run in the beginning of the system. We now switch to the configuration method which will reduce the provision time from 3m40s to 2m30s with
time sky launch -c min-aws --cloud aws -yTested (run the relevant ones):
sky launch -c test --cloud aws 'sudo apt install tree'pytest tests/test_smoke.py --aws(except for the azure issue in [Dependency] Drop Python 3.6 support, switch to Python>=3.7 and fix azure launching issue #1952)
