Install
The installation procedure is still being finalized. The path that exists today is: boot a live ISO, mount a target filesystem, and run setup.
setup is the Splux installer. It is not a generic SPS or LFS installer. It uses dialog screens, or the same choices from flags for scripts.
1. Download and verify
Get an image from download. For a source install use sps-live-tty.iso, not the slim image. Check it against SHA256SUMS.
2. Write the image
dd if=sps-live-tty.iso of=/dev/sdX bs=4M status=progress conv=fsync
Replace /dev/sdX with the USB device. That command erases the destination.
3. Boot and target disk
Boot the "SPS Linux live (Splux)" entry. The live system comes up on the console (or Plasma on the Plasma image). For QEMU, give the guest a writable second disk in addition to the CD. The live image never runs grub-install on its own.
4. Run setup
setup setup --plan --profile plasma-desktop --target /mnt --user alex setup --non-interactive --profile minimal --target /mnt --hostname darkstar
Profiles are minimal, server, plasma-desktop, and plasma-full. Init is a choice: systemd (default) or OpenRC. Those packages conflict. Guided partitioning is optional. grub-install still needs --install-bootloader and --disk.
The installer writes hostname, timezone, keymap, and a first user, copies bundled recipe trees when present, runs src update, and sget install. Packages are built from source on the target. A Plasma install compiles Qt and KDE and takes a long time.
