The userspace half is done and needed no root. This covers what does:
NOPASSWD sudo for infra-ops (ending the gx10 fleet exception), the docker
group, the CUDA toolkit for nvcc, and the NVIDIA Container Toolkit wired
into dockerd.
Unrun -- it needs one interactive invocation to supply the sudo password,
because no gx10 credential is vaulted and elway prompts via getpass. After
its first step lands, the box stops being an exception and later runs are
unattended.
Guards worth noting: the sudoers drop-in is validated with visudo -cf
before install, since a malformed one locks every sudo user out of a box
sitting on a desk with no out-of-band access; and cuda-toolkit is
installed rather than the cuda metapackage, so the working 580.173.02
driver is not replaced.
