Is your feature request related to a problem? Please describe.
Currently, our installer script is tested on limited environments. This creates a risk of compatibility issues across various Linux distributions (e.g., Debian, Ubuntu, Fedora, AlmaLinux, Arch). It's frustrating when the script breaks on a specific distro due to missing packages, systemd differences, or shell incompatibilities.

Describe the solution you'd like
Modify a GitHub Action or CI task we have for QEMU that:

• Spins up multiple virtual machines using QEMU for different Linux distributions.
• Runs the install.sh script in each environment.
• Reports success/failure along with logs for each OS variant.

Supported distros to include initially:

• Debian (11, 12)
• Ubuntu (20.04, 22.04)
• Fedora (latest)
• AlmaLinux / Rocky Linux
• Arch Linux (rolling)

Optionally:

• Run in headless mode with output streamed to logs
• Add retry or fallback mechanism if package managers fail

Describe alternatives you've considered

• Manual testing in local VMs — time-consuming and error-prone.
• Docker containers — not a perfect match for real init/systemd setups required by the installer.
• Limiting official support to Debian/Ubuntu only — not ideal for broader adoption.

Additional context
This testing setup will:

• Help catch errors earlier in CI
• Ensure wider compatibility
• Improve contributor confidence when modifying the installer
