Comment 2 for bug 2003027

I just got a Raspberry Pi 5 and after loading the Mantic image I noticed that the file /lib/sysctl.d/50-default.conf from systemd isn't present, causing the network interfaces to default to pfifo_fast.

This file is also missing from the build "ubuntu 24.04 LTS amd64 (daily) (20240210)" running as a VM under LXD.

I think this regression could be an unpleasant surprise for Jammy users when they migrate to Noble.

Thanks.
