Hi,
I am trying to implement DM-Verity for the rootfs. However, I am not sure
what the scope of DM Verity. I can see that given a root/sudo user, I can
unload the verity target, write to rootfs and format and load it again, is
it possible that this is normal that can be carried out using rootkits or
any privileged app?
Also, how can DM-Verity ensure that the system boots to correct rootfs if
rootfs was changed after an OTA?
Please help me to understand the actual scope of DM Verity
Thanks,
AP
