Hi,
I'm trying to run the Greengrass V2 core on the device as non root user. I installed the GGC without any problems. I want the Greengrass to be ran from ggc_user. I have /home/ggc_user/greengrass folder. I changed the service to use:
ExecStart=/bin/sh /home/ggc_user/greengrass/alts/current/distro/bin/loader
User=ggc_user
Group=ggc_group
This is all working but I'm getting some strange errors:

On my system I do not have sudo command (I won't be able to add it). Why greengrass wants to use it?
