Create kea runtime directory at startup in Yocto image

Question

I need to get Kea (DHCP server) running automatically at startup in my Yocto-based project. The Yocto recipe already includes an init.d script to start Kea automatically, however Kea requires a directory /var/run/kea to exist in order to run, so the startup script fails. Since directories under /var/run do not persist, this directory needs to be created at each startup. How can I accomplish this?

Answer 1

I just needed to add mkdir -p /var/run/kea to the kea-dhcp4-server script under init.d. (I had already tried this but forgot to set execute permission on kea-dhcp4-server in my .bbappend).
