Revert to the software that was loaded at the last successful request system software add command. The upgraded FreeBSD 11.x (supported in Junos OS Release 17.4R1) Junos OS image provides an option to save a recovery image in an Operation, Administration, and Maintenance (OAM) partition, but that option will save only the Junos OS image, not the Linux image. If a user saves the Junos OS image and recovers it later, it might not be compatible with the Linux software loaded on the system.
