Subject: [PATCH 13/20] host/rootfs: pass API socket as fd 3, not fd 0
Date: Thu, 04 Sep 2025 17:26:35 -0400	[thread overview]
Message-ID: <20250904-systemd-v1-13-2a63b790a913@gmail.com> (raw)
In-Reply-To: <20250904-systemd-v1-0-2a63b790a913@gmail.com>

Cloud Hypervisor might close this, and closing stdin is a bad idea.
