[Bug 2051358] Re: Start of systemd service on physical network devices using a udev rule has stopped working

[Franck Iaropoli]

** Description changed:

  Hi everyone,
  
  We have an issue with latest version of systemd on Ubuntu 22.04
  (249.11-0ubuntu3.12).
  
  We have a udev rule running a service (custom wpa supplicant) on physical wired network devices that is not working during boot process anymore.
- The same rule works fine with a usb dongle I unplug and plug back after the machine has started.
- 
- A colleague has rebuilt systemd package by reverting below patch and
- everything started working again
- 
- core/device: ignore DEVICE_FOUND_UDEV bit on switching root (LP: #2037281)
-     File: debian/patches/lp2037281-core-device-ignore-DEVICE_FOUND_UDEV-bit-on-switching-roo.patch
-     https://git.launchpad.net/~ubuntu-core-dev/ubuntu/+source/systemd/commit/?id=00f86f0b20f794f30aabe7181912d2ec2207e292

- This is causing an issue to access network when the machine is starting.

  Does above patch requires a change in the udev rule we are using ?
  
  Thanks in advance for your help.

  This is causing us an issue to access network when the machine is
