I don't want to force early via including graphics modules in initrd. One of the Shaman Penguins on the forum thread provided a workaround I can use until the real offender can be isolated and possibly dealt with: # systemctl cat display-manager.service ... # /etc/systemd/system/display-manager.service.d/override.conf [Unit] After= systemd-udev-settle.service Requires=systemd-udev-settle.service
