Looks good, just a small comment:

That comment seems wrong as you are selecting dbus and DYNAMIC_UDEV
which ends up selecting udev.

You added "Use " in front of sysv + systemd, but not busybox - And
"init" after busybox + sysv. I suggest you drop both so it becomes just
busybox/systemv/systemd.

You don't really need to select UDEV as it gets selected by systemd.
