remove "native" account, can be made if needed
ssh has "default" keys and host keys in root/.ssh

fix sftp-server path in openssh config

update grub to allow changing kernels with grub-set-default

Benefits:
Speed up boot on systems without the pcie card
Ensure modules are re-compiled for correct kernel on all boots

notes: udev loads in two stages: add and then bind.
ensure that rule for add contains systemd_ready=0

systemd will only try to attach once.

move lowlatency config into OAI image
move tuned config into OAI image

disable hyperthreading in OAI image

roll kernel back to non-hwe for compat with NI PCIe Driver
add apt sources.list for mellanox NIC drivers for better performance

split UHD build into separate stage for faster builds and smaller img
copy UHD artifacts into final image
download only needed sdr images

certain files, resolv.conf, hosts, etc, are mounted by docker
This prevents modification during build

We must run the container before exporting anyway
therefore, run "late commands" during runtime instead of build

late_commands script executes list of commands, then whatever
CMD is in dockerfile, or appended to the run command

to inspect, choose a shell, like /bin/bash
to export, choose a long enough sleep to copy fully
