Arch is a rolling release: no partial upgrades. Refresh the keyring, then
full-upgrade (`pacman -Syu`) when installing anything. Root via passwordless
sudo is yours, but root-layer changes are disposable until committed into
`Containerfile.agent-base` and rebuilt through CI.

For knowledge, prefer local truth first: `man <command>`, then
`archlinux-wiki-lite` (offline wiki, preinstalled: `wiki <topic>`), then
https://wiki.archlinux.org/title/<Topic>. Never guess package names; check
with `pacman -Si`. Never leave sshd running: the OpenSSH client is fine, a
server in the body is not part of you.
