This change updates how the lconfig arguments are constructed. This makes the update-ldcache more robust and ensures that folders are specified last if at al. Checks are also included for empty container roots at the start of the hook to simplify later checks. Signed-off-by: Evan Lezar <elezar@nvidia.com> |

NVIDIA CDI Hook
The CLI nvidia-cdi-hook provides container device runtime hook capabilities when
called by a container runtime, as specific in a
Container Device Interface
file.
Generating a CDI
The CDI itself is created for an NVIDIA-capable device using the
nvidia-ctk cdi generate command.
When nvidia-ctk cdi generate is run, the CDI specification is generated as a yaml file.
The CDI specification provides instructions for a container runtime to set up devices, files and
other resources for the container prior to starting it. Those instructions
may include executing command-line tools to prepare the filesystem. The execution
of such command-line tools is called a hook.
nvidia-cdi-hook is the CLI tool that is expected to be called by the container runtime,
when specified by the CDI file.
See the nvidia-ctk documentation for more information
on generating a CDI file.
Functionality
The nvidia-cdi-hook CLI provides the following functionality:
chmod- Change the permissions of a file or directory inside the directory path to be mounted into a container.create-symlinks- Create symlinks inside the directory path to be mounted into a container.update-ldcache- Update the dynamic linker cache inside the directory path to be mounted into a container.
