While installing AWS IoT Greengrass for Raspberry Pi, there is a need to create ggc_user & ggc_group as mentioned in Greengrass developer guide step 9:
sudo adduser --system ggc_user sudo addgroup --system ggc_group
Q1) Is it possible to use another user & group or customize? Q2) What other configurations will be required to change in raspberry pi setup or greengrass setup or AWS Console then to make greengrass work on pi?
EDITED QUESTION: if rename ggc_user name to XYZ_user, why do greengrass-sdk stop working? Do i need to use this new username on any other files or setup/config of greengrass?
