# Runtime + build essentials:
# - rsync: required for file backup/restore
# - ca-certificates: TLS
# - docker-cli: needed if you want to control the host Docker engine (via /var/run/docker.sock mount)
# - make: to delegate install logic to Makefile
#
# Notes:
# - On Debian slim, the docker client package is typically "docker.io".
# - If you only want restore-without-docker, you can drop docker.io later.
