Overlay filesystem performance across distros?
Attaching a debugger to a process?
Idk. Just some ideas off the top of my head. I don’t think it’s unimaginable to consider how docker is an increase in complexity and understanding.
I imagine one could install GDB in the container and connect to it remotely? Or from the container's shell?
IIRC, you just need to install gdb when you build your image and use `docker run -it bash` to run any shell commands in your container
Since the remote stuff is sometimes an incredible pain to set up and use, I usually install gdb and just use its CLI in the container. That's usually trivial in comparison, and it's a decent skill to learn regardless since so many debuggers use a similar CLI UX. It's extremely cross-platform and cross-language, so you can just jump on a new thing and be a wizard from day 1.
You can just use --net=host if you don't like it.

I've used docker on several distros and never noticed an issue with this.

This is also not an issue if you don't use bridge networking.
