Well, I saw a rather dramatic increase on disk usage when running podman
rootless.  Looked like podman did a full container image copy for each
docker file step instead of properly stacking incremental changes.
Didn't investigate why.

Therefore my "docker" looks like this:

   address@hidden ~# cat bin/docker
   #!/bin/sh
   proxy="https_proxy,http_proxy,ftp_proxy,no_proxy"
   exec /usr/bin/sudo --preserve-env="${proxy}" /usr/bin/podman "$@"

So, yes, podman can run our docker tests just fine, but the rootless
mode has some hickups still.

cheers,
