This device has booted from the backup JUNOS image.

This switch is booted off the backup partition and also happens to be on a different version of JUNOS then I want.

Is there a way I can repair the da0s1a partition, reboot and then

request system snapshot media internal slice alternate 

to get back to a good state?

Is there a different order of operations I should follow? Online blogs don't really account for the root partitions being different or that the version I want is on the bad partition.
