systemd-udev-settle.service 

This service actually does very little: it just waits for the device probing being done by udev to finish and then exits. It is also used by storage devices such as RAID and LVM, maybe a non-existent 3g Modem, USB ports, etc.

On my part, I have masked NetworkManager-wait-online, MOTD, apt-daily-upgrade, ModemManager, nmbd, etc since I don not use them.
