Is very easy to build the kernel without rust, and is the default scenario

Or a more old hardware friendly system like netBSD

Nowadays a lot of hardware works very well on Linux, the main approach of this vendors is not the compatibility (has guaranteed but as you say in a thinkpad you have the same compatibility), the approach is about a free software (or mostly free) firmware, and in this case, free and secure implementation for the firmware an all secureboor chain

Gentoo have both sides, the cool community and the suckless community xD You can check it in the telegram groups about gentoo

In my firs time with linux I install ubuntu (maybe 12.04, I dont't remember, it was gnome 2) in the only PC in my parents home, I delete windows, and we was using it 2 years without knowing what is a terminal and everything went fine, the problems appeard when I was discover the terminal hahahaha

Nah you can have x3 load per core without problem. The real problem is when you haven't got enough ram xD

This boards haven't got the rv23 necessary extensions, and aren't competitive, they are expensive for their performance. There only one attractive is the risc-v cpu for learning, etc

I think this can be a good idea in... 5 years maybe? It will only works on qemu, witch board suppose to have this things? I only know one board with all of thins things in ARM, risc-v is too young. I can't imagine a competitive risc-v board at the moment

No. The main diference is that you write a software for Android, it doesn't work in gnu/Linux (without extra layers), but if you write a software for steamOS, literally you are writing a software for gnu/Linux. SteamOS is an arch Linux modified to be immutable with a custom (and free) kernel with extra support that they merge after in mainline, with the steam app oppened by default. SteamOS use all the software stack for gnu Linux. Android develop their own stack and work different.

You can install gentoo-kernel-bin and everything works fine. About SystemD, you needn't systemd as init, but you need systemd as udev or other things. Only follow the guide with a non-systemd profile

afro samurai is a masterpiece

But you want to use systemd-boot? Obviously you need to install systems-utils if you want to install systemd-boot, but you can use grub or something else bootloader

UKIs are good for secureboot/measureboot, because you can sign the uki, and everything inside of it be validated for secureboot. If you really like to have a secure chain without a uki, you need to validate all the boot components. You can do it with grub and gpg signatures, but is more simple to use an uki and a efi bootloader like systemd-boot

Yes, it's a difficult situation to get out. I think the ecosystem is growing very fast, but enough fast for the ubuntu way? I don't think so

Yea this is what I was saying whan I talked about the risc-v ecosistem isn't competitive (at the moment). For me the bests boards at the moment are the based in the spacemmit k1, supports the majority of the rv23 profile extensions (not everything, and for this reason not will be compatible with the new versions for Ubuntu), and full rv22, including rvv 1.0. I have an orange pi rv2 (they use a renamed k1 for some weird reason), and works very well... For 50$, not for more

I'm using a orange pi rv2 and reading the patterson-waterman risc-v book (it's free): http://www.riscvbook.com/

I have other boards less powerful, but the rv2 is more funny and have the vector extension

In my opinion the hardest thing in linux is leave to use propietary or exclusive software for windows, the first think you must do is leave to use propietary software in windows, and when you can live without windows exclusive programs, switch to linux. You can start for ubuntu or other linux friendly distribution, doesn't care, afther the migration you can try other for curiosity without risk

Apparently the dbt for the Ubuntu image confirmed the x1 CPU a clone for the spacemit k1

With 8 or 16 GB of ram it would have been the best risc-v board excluding the milk-v pioneer
