Rozhodl jsem se, že konečně udělám další systém, tentokrát pro běžné používání na všechno a s aktuálními balíčky, které budu relativně často updatovat, protože to počítač upočítá a já uý nechci věci oddělovat a zápasit se zpětnou kompatibilitou.

Los padl na partišnu 12 - devAVR, kde sice byl zárodek systému, ale ještě ani jeden uživatel. Takže všechno špatně, zpátky na stromy, bude to Cobra2024
