Really pedantic nit here, but the cipher Salsa20 is called “Salsa20” and so reduced round versions are called e.g. “Salsa20/8”. However the ChaCha cipher is just called “ChaCha” so the specific-round versions are just “ChaCha20” or “ChaCha8”.

I feel like I just “actually it’s GNU/Linux”ed you there though... I feel bad, I’m sorry.
