ContainerImage.ActRunnerExtended

This image extends catthehacker/ubuntu:act-24.04 by including the following utilities:

• File templating
  • gettext (provides envsubst)
• ISO creation
  • genisoimage (generate cloud-init seed images)
• VM image building
  • qemu-system-x86
  • qemu-utils (provides qemu-img)
• VM image filesystem access
  • supermin (prerequisite)
  • libguestfs-tools (provides guestfish, virt-sparsify, etc)

It’s designed for use in self-hosted act-runners, to operate in environments similar to local QEMU/KVM-based pipelines.
