Use CoreOS Container Linux as the base for a home router, where the router and helpers for each network are separated into containers, using systemd nspawn.
The setup consists if a PCEngines apu2c4 powered with PoE.
The first ethernet port on the apu is used connected to the internet, the second is connected to a "trunk" port on my switch and used as a VLAN agregator. The third port is used for a management network and used to ssh into the apu.
apt install bash-completion vim git tmux kitty-terminfo debootstrap
At the moment containers need to be enabled by hand:
for c in /etc/systemd/nspawn/*.nspawn; do basename $c .nspawn | xargs -n1 sudo machinectl enable; done
Also if machines.target is not enabled:
systemctl list-units --type=target
Do so:
sudo systemctl enable machines.target
Also if a container times out on start edit its override:
sudo systemctl edit systemd-nspawn@<countainer name>
And add:
[Service]
TimeoutSec=600
If a container needs to start after another container add:
[Unit]
After=systemd-nspawn@unbound.service
