Driver podman does not provide a schema

Podman driver does have a schema and will always generate a warning.

WARNING Driver podman does not provide a schema.

Podman requires 'tmpfs' as dict not list

Molecule documentation refers to using tmpfs as a list. Podman only accepts dictionaries.

molecule.yml 

platforms:
  - name: 'tmpfs as a dict'
    image: ghcr.io/hifis-net/debian-systemd:13
    tmpfs:
      /tmp: 'rw,size=787448k,mode=1777'

platforms:
  - name: 'tmpfs not needed with systemd always'
    image: 'ghcr.io/hifis-net/debian-systemd:13'
    systemd: 'always'  # tmpfs not need if 'always'.

Podman database static dir mis-match

Podman will not migrate things out of /home to prevent existing pod breakage.

Error: database static dir ".../graph/libpod" does not match our static dir ".../graph/libpod": database configuration mismatch
# Reset podman and migrate.
podman system reset
podman system migrate

Cannot use ping from container

Some containers services require ping.

/etc/sysctl.d/net_ipv4_ping_group_range

0755 root:root

net.ipv4.ping_group_range=0 $MAX_UID

/etc/containers/containers.conf

0644 root:root

default_sysctls = [
  "net.ipv4.ping_group_range=0 2147483647",
]

Containers ignore graphroot and runroot

Graphroot and runroot are ignored in rootless containers and use following defaults if not defined:

XDG_CONFIG_HOME=${HOME}/.config
XDG_DATA_DIR=${HOME}/.local/share
XDG_RUNTIME_DIR=/run/user/${UID}
