OS: Ubuntu 24.04
I have searched this for a while and seems i can’t get my search terms right.
Back when ifuo/down system worked custom scripts were put under ‘/etc/network/if-up.d’ etc. Now ubuntu uses netplan. But where to put custom script? That would handle tc rules in my case. /etc/networkd-dispatcher/routable.d was told by internet but that just trows error during boot; ERROR:Unknown state for interface.
‘journalctl -u networkd-dispatcher’ says:

I think scripts in ‘/etc/networkd-dispatcher/routable.d’ or ‘/usr/lib/networkd-dispatcher/routable.d’ are not ran because networkd-dispatched do not get interface state.
Based on https://netplan.io/faq > ‘Use pre-up, post-up, etc. hook scripts’; routable.d is correct location in my case.
