hell no, oneshot orders too and it's even easier becaue it exists
completly and it takes you just 30 seconds to try it out or a little
expierience with systemd at all

the only thing where systemd can't wait is "simple" because there is no
forking and no exit and so systemd can't tell if the executeable is full
opertional

oneshot: no-brainer, ExecStart exists, next prdered service
forking: doble fork of ExecStart, next orderred service
notify:  mainpid even tells systemd "im ready, you can continue"
