After reading this answer, I thought it would be funny to roll my own init on Python, so I wrote this in /init-python
.
#!/usr/bin/python3
import os
import subprocess
# Make / writable!
subprocess.call(['/bin/mount', '-o', 'rw,remount', '/'])
# Became IPython (Now we're at it, get a good shell!)
os.execv('/usr/bin/ipython3', ['init'])
Then added init=/init-python
to the linux
line in GRUB config. It works.
So I was wondering now… how to power off or reboot my system with my homemade init?

It can be done with
reboot
function (man 2 reboot
).
