Beryl::Bootstrap::QemuInRescue

Bootstrap complet FreeBSD via mfsBSD-in-QEMU + post-install no-chroot.

Flux validé manuellement sur loulou le 21 avril 2026 :

. SSH rescue Linux → apt install qemu-system-x86 ovmf sshpass curl . Download mfsBSD SE (cache) . NOGO si BSD déjà sur le disque cible . Upload rescue-run-vm.sh via scp (évite Process.run stdin-pipe) . Exécute le driver shell sur le rescue (UN seul ssh outer, zéro nested côté Crystal → zéro hang macOS). Le driver : .. systemd-run QEMU UEFI (survit à la fermeture ssh) .. attend SSH mfsBSD .. pré-fetch txz + bsdinstall PRÉAMBULE SEUL (pas de post-install chroot) .. remonte ZFS + post-install HORS chroot ciblant /mnt (contourne Capsicum) .. unmount + poweroff . OVH API boot_from_disk + wait SSH FreeBSD (admin user)

Voir ADR-013 pour la justification détaillée du pattern no-chroot.
