Thanks yeah this is useful information.
I think what I’m doing is pretty wierd, I’m copying the Linux_for_Tegra folder onto the Jetson device into a docker container and from there i’m running apply_binaries.sh -r / to apply them to the docker containers “live” rootfs.
Had this working for the tx2 - although in that version there was no nv-apply-debs.sh - and its those deps that i’m running into issues installing with this read-only error mentioned above.
