I assumed this was a post about ChimeraOS, a gaming focused Linux distro, but it seems this is talking about a totally different Linux distribution with the same name.
“The system also has no relation to ChimeraOS, besides the unfortunate name similarity. ChimeraOS used to be called GamerOS and renamed itself to ChimeraOS later; however, at this point Chimera Linux was already in public development with its name in place.”
