[Discussion] How to use CUDA SDK installed on host?

Hi,
I run Fedora 39 on my base system, which has GCC 13.2 that is incompatible with all current versions of nvcc. Thus, I am trying to use distrobox to install a Ubuntu 22.04 container.

When I create the container with `distrobox create --nvidia --name ubuntu-nv --image ubuntu:22.04`, the directory `/usr/local/cuda-12.1` from the host system seems to be made available to the container, but for some reason it does not contain the sub-folder `bin` present on the host system.

When I create the container with `distrobox create --nvidia --name ubuntu-nv --image ubuntu:22.04 --volume /usr/local/cuda-12.1:/usr/local/cuda`, no CUDA folder is made available in the container for some reason.

Am I doing something wrong here? I am aware of the possibility to just access all files of the host via `/run/host`.

這個 issue 涉及在使用 --nvidia 旗標的 distrobox 容器中掛載 CUDA SDK。首先檢查 distrobox 原始碼中的磁碟區掛載邏輯，尤其是 NVIDIA 整合相關的部分。查看 /usr/local/cuda 等主機目錄是如何映射的。測試兩種命令變體，看看容器內部出現了哪些目錄。目標是了解為什麼缺少 bin 子資料夾，或者為什麼手動掛載磁碟區會失敗。
