Re: cephadm - podman vs docker

General complaint about docker is usually that it by default stops all
running containers when the docker daemon gets shutdown. There is the
"live-restore" option (which has been around for a while) but that's turned
off by default (and requires a daemon restart to enable). It only supports
patch updates (no major version upgrades) though that might be sufficient
for you.
