- **Advertencia:** el bootstrap de servidor crea un bosque nuevo. No restaura los SID, contraseñas ni relaciones de confianza del bosque anterior; para conservarlos se requiere una recuperación de bosque desde una copia de estado del sistema.
- `sgu-server-bootstrap-$Version.zip`: crea el bosque AD/DNS, OUs, grupo RDP, GPO, recurso `Packages`, broker mTLS y administración remota; se reanuda solo después del reinicio.
- `sgu-client-bootstrap-$Version.zip`: registra un certificado mTLS único, instala y valida el Credential Provider antes de unir el equipo al dominio, habilita RDP/WinRM y se repara al arranque.
- En clientes Hyper-V con dos NIC, el bootstrap selecciona la red privada sin puerta de enlace, solicita o acepta la IP fija del cliente y conserva en pantalla y archivo cualquier error de enrolamiento.
- `sgu-linux-client-bootstrap-$Version.zip`: une clientes Debian/Ubuntu o RHEL/Fedora/Rocky/AlmaLinux con realmd, Kerberos y SSSD. Solicita interactivamente la contraseña de unión y no instala el Credential Provider de Windows.
- `sgu-azure-infrastructure-$Version.zip`: despliega mediante Bicep una VM Windows Server 2025, red privada, IP pública protegida por NSG y Azure VPN Gateway P2S; también genera certificados por equipo y descarga el perfil de cliente.
- El bootstrap Azure conserva la IP privada administrada por la NIC de Azure, autoriza el pool P2S en los firewalls SGU y nunca publica LDAP, Kerberos, SMB, RPC, WinRM ni el Auth Broker directamente a Internet.
