Sir,
I am a full time system administrator at a hosting company.
Furthermore, I also own a VPS @ digitalocean.
I have more than a decade of experience using and administering Linux servers, wether VPS, Dedicated, Cloud, or even on premise servers.
I really love to do BASH programming as it is a simple yet powerful language.
I am sure I can help you with your startup script, wether it be systemd or sysvinit core based.
Can you please PM me ?
Regards,
