yeah, pretty much this, just don’t forget to hold shift while using the ellipse selection to force it to create a circle

edit: the steps in order are: Ellipse selection (hold shift for circle) -> fill with black -> shrink selection by X pixels -> new layer -> fill with white

I just made one, just need to merge those three layers and I’ll be done…

As a former arch linux guy, the solution to this is to be prepared by having a separate partition for home, and a bash script to reinstall f—ing everything again with a single command.
