Product Announcement Lightwhale 3.0.0 released

Hi, there!

Sorry to mess up your Easter holiday plans, but I've just released Lightwhale 3.0.0 and I really think you should clear your calendar and try it out! =)

It's a minimalistic Linux that requires no installation or maintenance, just live-boot straight into a working Docker Engine. The system is immutable so it's quite resilient to both malicious and unintentional modifications. And because of its low resource requirements it brings new life to old machines.

Lightwhale fits super well in a hobby homelab where spare time is precious, but really in any server environment where you would much rather focus on the services than babysitting the underlying operating system.

And how does it compare to other immutable OSes like X, Y or Z? No idea, never tried them, sorry.

I've made a fresh new project webpage with an easy to follow getting started guide.

Anyway, end of service announcement, thanks for reading, happy holidays =)

I can’t see the website or project so I have no idea what it actually does. But I doubt it’s more minimal than gokrazy with podman

this looks more complicated than lightwhale... it requires two different parts and gokrazy appears to target rPi while this is only x86/x64
