Problem statement
Why should I run hello.sh before a bigger helper.sh script?
hello.sh is the smallest possible delivery check in the helper.sh flow. It confirms that the host can fetch and execute a remote shell payload without immediately changing package sources, services, or filesystems.
That makes it useful as a smoke test before Docker installs, VPN setup, or any script that will need root privileges and a longer rollback path.
What to check
- Use it before larger install or migration scripts.
- Confirm outbound access and shell execution first.
- Treat it as the safest first step in a new host handoff.
