For public disclosure
5.8 Update the Field Agent
The Mini Field Agent’s operating system is a custom, embedded, Linux-based operating system called Yogurt that is built
using the Yocto Project toolchain. Both the Embedded Field Agent’s and the Virtual Field Agent’s operating system is
Ubuntu. Like many other Linux distributions, it is divided into a number of independently maintained and versioned software
packages. GE and the Linux community are continuously releasing new versions of these packages to provide feature
enhancements, bug fixes, and security patches.
GE strongly recommends that customers keep their Field Agent OS up-to-date.
In order to ensure that Linux package updates do not break the existing Predix functionality running on the Field Agent, GE
uses a daily continuous integration process to verify that updates remain compatible with all Field Agent hardware and Predix
software before they become available to installed Field Agents. Encryption and digital signatures are used to ensure that only
approved package versions are installed on each Field Agent, and that the specific versions used are kept confidential.
Customers can choose one of three methods for keeping their Linux packages up-to-date. Customers must select a method
while performing the one-time configuration of the Field Agent from its Field Agent Updater web page.
