Hello everyone,
I'm using yocto to create a custom linux image for a raspberry pi.
We have an "agent" that writes /etc/systemd/network/20-eth.network when the
final user wants to have a static IP address and we remove the file when
they switch back to DHCP.
After creating/deleting the file above we run `networkctl reload &&
networkctl reconfigure eth0`.
We mount the overlayfs with a custom .mount unit.
We've noticed that DHCP works fine if systemd-networkd starts before we
mount the overlayfs but it doesn't if systemd-networkd is
restarted/reconfigured after the folder is mounted or started after the
overlay .mount unit.
Every interface DHCP fails with:
DHCPv6 CLIENT: Failed to set DUID-EN: No medium found
eth0: DHCP6 CLIENT: Failed to set DUID: No medium found
We're using systemd 246 (246.9+) and we're planning on upgrading to 247.6
soon.
Is this expected? Is it somehow incompatible with overlayfs?
Or maybe it's not related to the /etc filesystem and it's something else?
Any help is really appreciated.
Thanks
