Recentemente estava testando várias distros, inclusive diferentes sabores do Manjaro, mas percebi algo que estranho que se repete em todas... O boot demora a quase a mesma coisa em todas as distros e/ou interface gráficas. Como resolvi me manter no Manjaro permanentemente, gostaria de saber o que fazer pra melhorar o tempo de boot? Não tenho SSD infelizmente, mas mesmo assim acho que é possível desabilitar alguma coisa que esteja sendo iniciada e fazendo demorar mais do que o normal. Para vocês terem noção, eu desativei o bloqueio de tela e coloquei login automático.[ariel@ariel-pc ~]$ systemd-analyzeResumo: 47 segundos. As vezes chega a 52, 50, 48 e fica nessa média.
