"error-prone" means bugs are more likely than the alternatives. It doesn't mean that the alternatives completely eliminate the possibility of bugs. Come on.

It doesn't need to be, but there are some advantages in being able to have system startup scripts in the same language that you do one-liners in at the terminal.
