IIRC that’s not accurate. You only need that “pro feature” if you want to be able to _apply activate kernel updates without rebooting. Unless you have that requirement and an armada of devices matching that profile you don’t need to pay anything.

You’re right. But I’d rather have limited Linux options than no option at all.

Testing a normal Linux installation sounds like a good idea. In my opinion it’s better to transition to Linux than switch. That way you can go back to your previous system setup and see what you are missing or need without having to open your computer and swap hardware. If you can add the old or new SSD as an external drive and so that you can can boot then your plan might work out.

I just can’t be bothered to switch when my current distro worked just fine for me for the last 20 years. I have no time to experiment anymore, I just want to get things done.

So how did it work out for you? Did bcachefs manage to perform any miracles?

You can’t lose what you never had, though. ;-)

Looks like the Gnome Disk Usage Analyzer but for KDE.
