It's not dependent on DM-Verity, that's just one possible integrity verification mechanism, and one of two supported in this initial version. The other is 'boot_verified' for a verified or otherwise trusted rootfs. Future versions will support FS-Verity, at least. IPE was designed to be extensible in this way, with a strong separation of mechanism and policy. Whatever is implemented for NFS should be able to plug in to IPE pretty easily. -- James Morris <jmorris@xxxxxxxxx> -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
