dramatically speeds up my boot time because it was the last service (for me) that depended on udev-settle.service udev-settle isn't needed for modern system initialization but some oldschool services (mdadm/lvm/cryptsetup) depend on it so they can just enumerate devices instead of having to react to changes dynamically. In NixOS these things are usually already taken care of during stage 1 (early ramdisk) if you use them.
