Calamares Configuration for BlossomOS

This repository contains the Calamares installer configuration for BlossomOS, a Fedora-based Linux distribution featuring KDE Plasma.

How it works

The installer guides the person setting up the machine through locale, keyboard, and partitioning only — no user account is created during installation. On first boot, plasma-setup launches and lets the end user create their own account. This makes BlossomOS suitable for OEM installs where someone else sets up the hardware and hands it off.

What gets installed

• KDE Plasma desktop environment
• GRUB bootloader (UEFI and BIOS)
• Flatpak with Flathub for app installation via KDE Discover
• Plymouth boot splash (spinner theme)
• Timeshift for BTRFS snapshots
• BlossomOS branding and custom packages from the BlossomOS RPM repository
