[gentoo-user] Kernel modules and security

Hello list, Years ago, in the days of Yggdrasil I think, the received wisdom was that enabling kernel module loading was a bad idea because an attacker might be able to load malicious software directly into the kernel. No modules --> one more attack route closed. What is the current thinking

[gentoo-user] Kernel modules: initramfs vs. /lib/modules

Hi all, I am trying to understand a bit initramfs and genkernel and I have few (basic) questions. I understand that one must have in the initramfs those modules which are required to boot the system, for instance to access /dev . Now: - can a module be present both in the initramfs and as

[gentoo-user] Kernel Modules

Hello list, I was wondering if it is possible to have a tool with which it would be possible to have external modules installed for _all_ kernel versions in my computer. Now I am using 2.6.38 kernel, but would like to try 2.6.39 and the thing is that I would like to have tp_smapi and phc-intel
