Build out the home-lab OpenBAO deployment beyond the basic node: - docker-compose: add openbao-unsealer sidecar; main node now transit auto-unseals against it (seal config kept in gitignored config/seal.hcl) - policies/admin.hcl: non-root admin policy; per-engine rules for ssh/pki/pki_int/totp/transit - Internal two-tier CA (pki/ root + pki_int/ intermediate) issues the openbao.famfi.home leaf Traefik serves; root CA published under ca/ - scripts/ + systemd/: daily cert renewal and Raft snapshot backups (both instances), with scoped tokens stored outside the repo - README: full runbook (auto-unseal, PKI, renewal, backups, DR/restore) Secrets (init/unsealer keys, tokens, seal stanza) stay gitignored.
