No clue

So how do I totally disable so access once logged in doesn't timeout in 5 minutes putting machine in sleep mode which disables remote access too? At 16 watts, it can run 24/7/365.25 doing its job which is as a backup server. Thanks all.

Quick retest in the container if I also install normal Debian kernel: root@ranc:~# apt install linux-image-arm64 wireguard Installing: linux-image-arm64 wireguard Installing dependencies: linux-image-6.12.48+deb13-arm64 wireguard-tools Suggested packages: firmware-linux-free linux-doc-6.12 debian-kernel-handbook openresolv | resolvconf

But why the Real-Time kernel and not the normal (linux-image-arm64) kernel package? I actually did run it as a systemd-nspawn -bxD <btrfs read-only snapshot> , so Armbian as container and host vanilla Debian. The actual kernel is then 6.12.48+deb13-arm64, but indeed the Armbian userspace (rootfs tree) has a few others/custom kernels installed only, so standard kernel package is missing.
