I use Manjaro, but I run it like vanilla Arch (for example pacman/yay and not pamac). I find this to be a sweet spot for me - rolling releases are so incredibly nice, and Manjaro being slightly slower than Arch is good from a stability standpoint in my experience.

I use ZFS all over the place, including the root storage pool on my home server, which has overall been a great experience with systemd-boot.

I’ve been wondering about this too - sometimes it subscribes immediately, sometimes it gets stuck pending. Hopefully the pending ones work themselves out per the other comments…
