Tweak machine.py component to allow rebooting and shutting down from mainsail GUI on a runit based distro ( just tested on voidlinux)

[engelsheidt]

Hello! I have been using klipper-moonraker-mainsail for around 1 year on a thinclient (voidlinux), i manually installed them and have been trying to make the host control work( via Mainsail´s GUI) , initially moonraker didn´t let me execute the reboot command because it detected the thinclient as a container because of the following:

[common.py:build_error()] - JSON-RPC Request-Error -Requested Method: machine.reboot. Code:400, Message: Cannot reboot within a 1xc container

I bypassed _check_inside_container (inside machine.py) by commenting the following lines:

def _check_inside_container(self) -> Dict[str, Any]:
cgroup_file = pathlib.Path(CGROUP_PATH)
virt_type = virt_id = "none"
if cgroup_file.exists():
try:
data = cgroup_file.read_text()
container_types = ["docker", "lxc"]
for ct in container_types:
if ct in data:
#self.inside_container = True
#virt_type = "container"
#virt_id = ct
logging.info(
f"Container detected via cgroup: {ct}"
)

After that moonraker gave me another error: "Container detected via sched", so i went back to machine.py and added "runit" to:

if proc_name not in ["init", "systemd", "runit"]:

Then commented and added the following to machine.py:

async def shutdown(self) -> None:
#await self._exec_sudo_command(f"systemctl {self.shutdown_action}")
await self._exec_sudo_command("poweroff")
async def reboot(self) -> None:
#await self._exec_sudo_command("systemctl reboot")
await self._exec_sudo_command("reboot")

Finally , at the end of the sudoers file i added:
pi ALL=(ALL) NOPASSWD: /usr/bin/halt,/usr/bin/poweroff,/usr/bin/reboot,/run/runit/stopit

Rebooted the thinclient (via ssh) and the host control works for now via mainsail GUI.

Klipper and moonraker run as user services, nginx as a root service.

I understand that my method to achieve the result is not ideal, that´s why I'm requesting the feature.

The user service directory looks like:

/etc/sv/runsvdir-pi/run

#!/bin/bash
exec 2>&1
exec chpst -u pi:"pi:dialout" runsvdir /home/pi/service

The klipper user service file contains:

~/sv/klipper-pi/run

#!/bin/bash
export HOME="/home/pi"
exec "$HOME"/klippy-env/bin/python "$HOME"/klipper/klippy/klippy.py "$HOME"/printer_data//logs/klippy.log -a /tmp/klippy_uds

The moonraker user service file contains:

~/sv/moonraker-pi/run

#!/bin/bash
export HOME="/home/pi"
exec "$HOME"/moonraker-env/bin/python "$HOME"/moonraker/moonraker/moonraker.py -c "$HOME"/printer_data/config/moonraker.conf -l "$HOME/printer_data/logs/moonraker.log

Running klipper and moonraker using python3

Finally adding the option to specify custom reboot, shutdown and system update shell commands on the .conf file would be amazing .
