Root persistent disk and non-root persistent disk in google cloud persistent disks

In GCP I came across creating disks and attaching them to a VM. There are two terms:

  1. root persistent disks

  2. non-root persistent disks

According to my understanding:

root persistent disks contain the OS images and these can be used (boot files)

non-root persistent disks are created such that applications use them for their operational purposes

If I mount the same root persistent disk to two different VMs, and after that if I make modifications to the system files in root persistent disk and reboot both the VMs, does the changes get applied in both of the VMs?

You can't attach one root (boot) disk to more than one VM -- that's a 1-to-1 relationship.

You can create multiple VMs from the same image, but that creates copies of the image on independent disks.
