[systemd-devel] Require a systemd.unit to finish completely before other services(units) are started

[george Karakou]

Hi list, how are you all? I hope everyone is doing well.
I have a long starting unit that executes some(many actually) scripts 
and with the parallel nature of systemd init process it doesn't fully 
start up before some other units i have starting after it. Meaning 
"After=" directives in [Unit] section don't fully fill my needs here.
Is there a workaround? I understand that this demand somewhat violates 
the parallel principle of the systemd init daemon but can it somehow be 
serialized?
Thanks for any advice.
