I finally did it. I installed Arch linux + Unity 3D + VSCode + budgie + vertex + sddm-deepin in virtualbox....

What a fucking journey and a half that was.
Now to install on an ssd for real...

My thoughts on the process:

1.) This is not for the faint of heart.
2.) Be preapred to devote some time getting it all right.
3. This was actually quite a rewarding process.
