Removing the toolchain is an old, common misconception whose originator |

I would love to meet and slap some sense into. |

What exactly are you defending against? If the server is compromised, |
| 13 |
it's game over - they'll run whatever code they want, be that [highly |
| 14 |
unlikely] compiling a binary to attack further or [highly likely] use a |
| 15 |
pre-compiled static binary of their own. If you don't have a toolchain |
| 16 |
and they must have one, they'll download a static one and bootstrap it. |

Better to learn the use of a good access control system like the |
| 19 |
grsecurity RBAC that is integrated into hardened-gentoo to prevent |
| 20 |
misuse of the toolchain than to go through fragile and unsupportable |
| 21 |
gyrations trying to prevent a phantom threat. |
