Comment 7 for bug 1914062

Investigating the issue, udev fails to enumerate devices in the lxc environment when udev_enumerate_add_match_is_initialized is called. The same test program works in a focal instance.

Discussing the issue on the LXD channel it was raised that the systemd udev changes in 247 could be creating problems.

The network-manager 1.26 version works because the udev support was wrongly disabled, which was fixed in that commit
