I don’t know about LVM but hostname was configurable in the old/current installer, this is news for a new installer to replace the old one.

I think Pixelorama (I’m on mobile right now so don’t want to drag up a link) is also FOSS and has a more comparable feature set.

FreeCAD is probably what you’re looking for, it had a bad UI but just released 1.0 recently and is pretty decent now. Also I really recommend checking Pixelorama over libresprite for a FOSS pixel art tool.
