Indeed, you can just write your own custom /system.yaml file with the hyprland package (or no WM/DE for that matter). This guide describes how you can do that: blendos.co/install/post-install/intro/ (use the ‘custom’ track and add ‘hyprland’ to the package list)
Ooh, not just yet (in essence, it’d be hard to migrate over from the system used in Fedora Atomic to that used by blendOS) :( We’re working on a migration script for users from regular ole’ Arch Linux, though.
Oh yep, they are declarative, and that’s what we’ve tried to implement with /system.yaml. pacman hooks and grub configs can be defined through /system.yaml (through a combination of the packages and commands arrays), but Plasma config is per-user and so wouldn’t be possible to declare unfortunately :( you can declare GNOME config though, fwiw
Oh, blendOS uses cloudflaremirrors.com during installation, which points at the Arch mirror it thinks it closest to you, and installation should be quite fast in North America (the blendOS package repo’s hosted in Germany, but it shouldn’t be too slow and doesn’t host too many packages required for installation). However, I do plan to make that configurable (as an option for users that know what they’re doing, or perhaps through a CLI installer for advanced users), and might implement it in the coming few days.
oh yep, should’ve clarified, /system.yaml’s, as the name might suggest (lol), for system-wide config only, and GNOME just so happens to support system-wide config; we used to have a utility for declaring config for individual users akin to home-manager in blendOS v3, but dropped it with v4 since that wasn’t used much; still might make a return though :)
Arch Linux, made immutable, declarative and atomic: blendOS v4 released (blendos.co)
