base-minimal

This is a CentOS Stream 10 Bootable Container that is minimal and contains the following packages:

Image size: 905 MB

1. kernel
2. bootc
3. systemd
4. podman
5. polkit (we use run0 and not sudo)
6. NetworkManager (auto-configure networking)
7. tailscale

There's a helper service file that will run /usr/bin/tailscale up --auth-key=${TS_AUTHKEY} --hostname=${HOSTNAME} --ssh if /etc/default/tailscale exists, which you can copy in your derived image.

There's more work to be done, particularly:

1. Harden the configuration
2. Split tailscale into another image
3. Investigate any another minimalization opportunities.
