Re: Start IOC automatically at boot

[Donny Domagoj Cosic via Tech-talk <tech-talk at aps.anl.gov>]

Hi Yong,

Thank you very much for your quick response and thank you for creating 
systemd-softioc and sharing it with the community. With your advice I 
got it working. procServ was not successfully installed and naturally it 
did not work. Once I installed procServ, everything works beautifully.

Thank you,
