[systemd-devel] Systemd not able to spawn Exec permission denied

[Krunal Patel]

Hi,



      We have total 6 servers . 1 server is started with switched-root system option. Where sdc.service through systemd running fine. But other 5 servers, systemd is running with –switched-root option where we are not able to start. I am not sure  if systemd is corrupted or some other issue.



System unit are as below:



sdc.service
