Install error when answering yes to Pull Malcolm images with podman.

[merll002]

Bug description
When choosing podman as the container runtime engine, answering yes to Pull Malcolm images errors as the script tries to use the --quiet flag, which is not implemented in podman.
Removing this flag fixes the issue.

Malcolm Version:

• Version v25.02.0

How are you running Malcolm?

• Podman on Linux

What version of podman are you using?

$ podman --version
podman version 5.3.2

$ podman pull --help 2>&1 | grep quiet
  -q, --quiet                        Suppress output information when pulling images

[merll002]

podman version 5.4.0

podman pull --help 2>&1 | grep quiet returns -q, --quiet Suppress output information when pulling images confirming that the flag exists, however the podman-compose command does not support it.

The command that is run by the script is:
/usr/bin/podman-compose -f /home/leo/malcolm/docker-compose.yml --profile=malcolm pull --quiet

[mmguero]

Ah, understood. I'm generally using podman as a backend for the docker compose command which is why I didn't catch it. Thanks, I'll get a fix in place to handle that case.

One unrelated question, what's the difference between Malcolm ISO and Hedgehog ISO?

[mmguero]

The Malcolm ISO (docs here and here) installs a Debian-based Linux operating system which includes Malcolm.

The Hedgehog Linux ISO installs a Debian-based Linux operating system which contains code and configuration to capture traffic on a network interface and forward network log metadata on to a Malcolm instance.

In cases where there is not a need for multiple capture points, and/or network traffic flow is low, a Malcolm installation can also handle the traffic capture all by itself, without needing a Hedgehog Linux capture sensor.
