Let me ask something. Say, a person is 20 years old. Newbie. Using the Handbook and trial'n'error method he finally gets it installed. If he has to do it several times before he gets the desired result - I see no problem. After that he'll know his way around and for next 50 years he does not need any improved installers.The first problem is a sole software problem that can be fixed. The second problem however cannot be fixed, cause there is a subtle difference between a newbie and a person strictly unwilling to learn anything while expecting everything.
So why it is so important to pay so much attention to that one day he is struggling? Versus decades long use of FBSD where he will have problems, indeed, but all those future problems have nothing to do with sysinstall?
Is FreeBSD aimed at noobs or users?
