The beauty of the WebUI is that it abstracts all of that away. You don’t
have to be in the know about the inner works and create pools and vdevs by
hand. Though it might be handy in case something breaks in an unexpected
way.

It’s called RaspberryPi OS (formerly knows as Raspbian). It has the kernel,
some start scripts and settings files that control which stuff to load at
boot. Pis boot differently to x86 hardware; there is no Grub & co.

I don’t particularly like Debian’s apt, which is why I’m also experimenting
with Arch on arm, Arch being my favorite distro for my everyday these days.
