Sandboxing with Smolvm

smolvm is a microVM system that is extremely fast at creating microVMs based on an oci image.
I started with holycode and stripped a bunch of tools and complexity.
I then switched it to a Fedora base image so I could add rootless podman, bootc and qemu.

To make this a simple part of my daily workflow I then created some bash functions and add them to my $HOME/.bash_profile

Now I have 3 simple functions available.

First of I want to check that I have all the latest packages in my debian system.
