I would have to botagree and disagree with this. We do want it to be easy for |
| 16 |
people to not "fall in the pit". However, grsecurity is a "security" |
| 17 |
enhancement. We do want the defaults to be secure. Where does one draw the |
| 18 |
line between these goals? I am certain I would recieve agreement if I said |
| 19 |
that we all have a different viewpoint on the "correct" or "appropriate" |
| 20 |
answer to that one. :-) |

Ah, I missed that, too. |

Because sshd is a tool to open a hole into your machine that allows people to |
| 32 |
remotely run whatever they want to. Under WinNT/2000/etc. ACLs on filesystem |
| 33 |
object (i.e.directories) are far to easy to abuse this way without realizing |
| 34 |
it. I could give examples, but I will hold off unless someone is really |
| 35 |
confused about this. |

That sounds reasonable to me (but I do not know that this is "the" truth). |
