Простой способ установки Talos Linux на любую машину и у любого провайдера

Обычно Talos Linux предоставляется в виде набора готовых образов под различные системы. Стандартный метод установки предполагает, что вы возьмёте подготовленный образ под конкретное облако или гипервизор и просто создадите из него виртуальную машину. Если же говорить о физических серверах, то предполагается, что для загрузки образа Talos Linux и последующей установки вы будете использовать ISO или PXE. К сожалению, это не работает, когда речь заходит о провайдерах, которые предоставляют преднастроенный сервер или виртуальную машину без возможности использовать кастомный образ или даже ISO для установки через KVM. В этом случае ваш выбор будет ограничен лишь теми дистрибутивами, которые предлагает облачный провайдер.

Was playing with #kexec and getting a hang/blank screen when attempting to reboot.

Guess what: the only person on the intertubes that also has this problem is another #Guix user:

Debugging tips welcome!

Oops, I fixed #IBM's broken #PowerPC64 #Linux #kexec code again ;-) https://youtube.com/live/-BV4IpW5aLI #openfirmware #t2sde #opensource

#Fedora40 #rebuild #kexec

I tried to #kexec again today. Things didn't seem to appreciate it, namely Sway did not want to start back up after I logged in.

@natty #systemd #kexec is one of my favorites to limit downtime from kernel updates.

The previous server had a horrible remote console, let's say I cannot boot a cd.
(it is a supermicro which can only boot an iso from a cifs share so no iso boot capability, right? ;-)

Found this little bit of awesomeness:
https://github.com/Tharyrok/kexec-remote-debian-install
I can start the #debian #installer with #kexec from the running system. Then I am wiping the disks from the installer.

I took another look at the vendor's asm code and the SiFive U7 core manual. Lo and behold!

Let me tell you a secret:
Enabling interrupts allows for triggering them. 🙃

So here we have both harts. Woop woop! 🥳

I have rebased onto #Linux HEAD (6.2 some RC) which has a lot of patches already and it's very close to a working #kexec on the #JH7100 / #VisionFive 1 now.

It says bye, but never hello again. :3 Sooo close!

@omenos @somegirlprivacy @e33io #kexec is great when it works and does what it's supposed to do. But I've also had it cause the need for the reboot (by crashing) that I was trying to avoid in the first place by calling it.

@somegirlprivacy @omenos @e33io The ostree flavors of #Fedora recently got an --apply-live for rpm-ostree update. It's not a desktop distro, but #TalosLinux uses #kexec to boot into a newer kernel and runtime live without reboot.

RT from Daniel Maslowski aka CyReVolt 🐢 (@OrangeCMS)

In today's stream, let's have a closer look at #kexec, and that be our last detour. I'll start with some news regarding the #VisionFive, #oreboot, #RISCV and #UEFI.
We shall get back to @oreboot_org and @rustlang things eventually.

See you at 20:00 CEST!
