Post #2485488

Finally got this into a nice state (and bursting with features): schupfn is a "boot a toolbox to a VM" script. Create your toolbox, work in it normally and then run `schupfn create $name && schupfn enter $name` to boot into a VM based on that toolbox. Only PWD is exported by default and everything else is discarded on VM shutdown. Great for e.g. letting an agent go yolo without worrying - after all it only has access to directories you explicitly give it. https://github.com/whot/schupfn
