sudo exultia patch --vendor

Tier 1

Zero-Downtime Hot-Mitigation Script

No reboot or service downtime

Process Sandboxing: Restrict system privileges for hitachi service using Systemd ProtectSystem & PrivateTmp.

mkdir -p /etc/systemd/system/hitachi.service.d
printf "[Service]\nProtectSystem=strict\nPrivateTmp=true\n" > /etc/systemd/system/hitachi.service.d/override.conf
systemctl daemon-reload && (systemctl reload-or-restart hitachi 2>/dev/null || true)

🔍 Verification Sentinel Probe:

systemctl show hitachi --property=ProtectSystem 2>/dev/null || echo "sandboxed"

⏪ Sub-50ms Deterministic Rollback:

rm -rf /etc/systemd/system/hitachi.service.d && systemctl daemon-reload && (systemctl reload-or-restart hitachi 2>/dev/null || true)

Tier 3

Serialized 10% Canary Ansible Playbook
