Hi, I’m in a process of making fast, (extrenely) secure, and modern laptop. Currently I have Arch Linux with encrypted root partition (unlocked with Nitrokey or long password), secure boot, linux-hardened, firewalld, etc.

I’m running linux-hardened with custom config. I enabled AMD SME, kernel lockdown, added some xanmod patch for more specific cpus, and disabled some unnedded drivers (only those that I’m 100% sure I don’t need - Intel, NVidia, Microsoft, Google, Amazon, Virtio). Currently it takes ~50 minutes to recompile the kernel. Are there any tutorials what drivers to disable to speed up this process? After doing that I will try to compile it with -O3 and LTO. Do you know any patches for performance?

I’m planning to enable encrypted swap, install ClaimAV and install flatpak versions for every non open-source app I have.

I also want to have SELinux. Does anyone know where can I learn it? I had it on Fedora and it was not fun using it.

What are other ways I can make my laptop more secure?

    Look at secureblue for more things

    • hardened malloc (preloading is somewhat complex for flatpaks)
    • maybe more kargs

    That custom kernel sounds very cool. Not sure if replacing it works on Fedora Atomic, would be very much needed

    SELinux confined users is also very important, SELinux is kinda contradictory to flatpak though, as they do the same things often and Flatpaks often dont work because they are not built for it.
