toolbox Add ability to mount volumes

Is your feature request related to a problem? Please describe. I use toolbox in fedora silverblue. I want to install dotnet sdk into a toolbox and than expose it to host for using with IDE. I can call dotnet command using toolbox run, but I also need access on host to files of sdk that are installed into /usr/lib64/sdk/dotnet.

Describe the solution you'd like This can be solved with volumes: I will create /home/user/dotnet:/usr/lib64/sdk/dotnet mount and use it in my IDE

Describe alternatives you've considered I tried to mess with podman:

add volume to an existing toolbox (not possible)
create a new container from toolbox image (but to be usable toolbox must configure this container first, and I didn't figure out how to do this)
commit existing toolbox container and run a new one from this image (throws errors on starting and fails)

Additional context There was a PR #100 that can support this, but it was closed without implementation many years ago

you and me both buddy, I just wanted to use scrcpy from inside a toolbox/podman container and I can't, I would really want to mount devices to an already created container, but Idk why that's not a feature by now (2025)

I have a similar request, but for allowing to mount other partitions, beyond /home/<user>, inside the container.

Working with large source code base (kernel) take some space, and having it in a different partition, outside /home/<user> is not unusual, thus having the ability to map volumes on enter or create time would be really helpful.
