update.sh is main script in every firmware update for edge. The original post refers to allmine update, so that after installtion of allmine all add-on programs writing to eink would work without need for root privileges

You actually did exactly what is needed. start_epd.sh is executed by system at startup, so you added a call to eink_permissions.sh that will take care of setting permission of /dev/fb2. Since you added contents manually, you do not need a backslash before last character ('&' instead of '\&'), I am not sure if having & escaped would change intended behaviour, better delete it. Also make sure that eink_permissions.sh has execute permission set, do 'chmod +x eink_permissions.sh' on it.
