If you're considering SELinux, please follow the instructions at |
| 13 |
http://hardened.gentoo.org/selinux/selinux-handbook.xml?part=2&chap=1 |
| 14 |
|

There's a little more to it than emerge system/world: |
| 16 |
- Your /tmp might need a specific mount option (in /etc/fstab) |
| 17 |
- If you use LVM or XFS, you need to take specific measures if you want your |
| 18 |
system to bootup properly |
| 19 |
- You need to build a SELinux-aware kernel as well |
| 20 |
- You need to install SELinux utilities |
| 21 |
- You need to relabel the system |
| 22 |
etc. |

That said, my opinion on a server is the same as with Matthew: use hardened |
| 25 |
with the options given (grsec, selinux) and perhaps even TPE (trusted path |
| 26 |
execution). |
| 27 |
|
| 28 |
Also consider hardening your system settings-wise. I would appreciate if you |
| 29 |
take a look at |

http://dev.gentoo.org/~swift/docs/previews/oval/gentoo-xccdf-guide.html. |

With the instructions given, you can even have your system validated (as far |
| 32 |
as possible) automatically. |
