You have not heard of it? Well, you're replying to someone who's using Arch. With Arch, you get into trouble all the time, but if you're well versed with Linux (and Arch) you can fix it.

I'm using Arch, and ZFS, on my work laptop. A month ago, when I update my kernel, boom I had to use Systemrescue because it would no longer boot ZFS root. And of course just at that day I lost my Ventoy USB stick (probably my 2 y.o. son got rid of it ...)
