I don’t think you can lump Endeavour and Garuda together. Yes, they’re both based on Arch but Endeavours basically is Arch with a GUI installer and sane defaults while Garuda changes a ton of things and adds a ton of customisations that make it very different from a plain Arch (or Endeavour) system.
Not in this context. Curious can have the same meaning as “kurios”, as it does here.
