"GendBuntu" is an atrocious name, and it doesn't sound good in French either (perhaps even worse). I don't know why they insisted on referencing Ubuntu in the name. GendarmOS would have been fine, or GendarmeSE to be more correct.
gendarme from "gens d’armes" to "gens d'ubuntu" (people of ubuntu) which, pronounced quickly would become "gendbuntu" is ok for an os name for gendarmerie
if only they went with arch to call their os "gensdarc" to play with the name Jeanne-d'Arc 🤭
