A sentence in section 2.d. contains an extra 'in' and should probably say 'to' instead of 'from'. "The /etc/securetty file allows you to specify which tty (terminal) devices root is allowed to login in from." should read "The /etc/securetty file allows you to specify which tty (terminal) devices root is allowed to login to." or, if you're a pedant like myself, "The /etc/securetty file allows you to specify to which tty (terminal) devices root is allowed to login." Reproducible: Always Steps to Reproduce:
Yes, I know that sentences should not end in prepositions. It happens throughout our documentation though, so one more instance will not be the death of us. I fixed the typo and left in a preposition.
