Right, they said they're on a macbook so unless they're going out of their way to run Linux bare-metal it has to use a VM. And AIUI there are extra footguns in that situation, especially that mapping volumes from the host is slower because instead of just telling the kernel to make the directory visible you have to actually share from the host to the VM.
> Shared folders are designed to allow application code to be edited on the host while being executed in containers. For non-code items such as cache directories or databases, the performance will be much better if they are stored in the Linux VM, using a data volume (named volume) or data container.
