Euri Linux — Horizon

a Linux distribution built from source. LLVM. musl. dinit. XBPS.

not a fork. not a respin. built.

note: when Horizon enters beta, the master branch will be archived and horizon will become the default branch.

---

what is this repo?

this is the ISO build configuration for Horizon. it contains:

• config/horizon.yaml — ISO build config (packages, users, services, bootloader)
• config/ — additional config files injected into the ISO

it does not contain the package build system (horizon-packages), the ISO framework (euri-mklive), or the installer (euri-installer). those live in their own repos.

how to build

option 1: euri-mklive TUI (recommended)

git clone https://git.euri-linux.pl/Euri-Linux/euri-mklive.git
cd euri-mklive
pip install -r requirements.txt
python -m euri_mklive

the TUI walks you through distro selection, package list, users, services, and bootloader. then builds the ISO.

option 2: manual (xbps + mkisofs)

if you don't want euri-mklive, you can build the ISO manually:

# 1. create rootfs
sudo mkdir -p /tmp/horizon-iso/{rootfs,boot}

# 2. install packages into rootfs (requires configured xbps + local repo)
sudo XBPS_ARCH=x86_64-musl xbps-install -r /tmp/horizon-iso/rootfs \
  -R https://pkgs.euri-linux.pl/x86_64-musl \
  base-system horizon-dinit-services linux7.2 sway NetworkManager

# 3. chroot and configure
sudo chroot /tmp/horizon-iso/rootfs /bin/bash
# set hostname, locale, create user, install limine/grub, etc.
exit

# 4. build ISO with xorriso
xorriso -as mkisofs -o horizon.iso \
  -b boot/grub/eltorito.img -no-emul-boot -boot-load-size 4 \
  -boot-info-table --grub2-boot-info --grub2-mbr /usr/lib/grub/i386-pc/boot.img \
  /tmp/horizon-iso/rootfs

this is not the recommended path. euri-mklive handles a lot of edge cases (initramfs, bootloader setup, locale, dinit service enablement) that you'd have to do manually.

p.s. adeolu if you somehow found this — horizons almost done lol. 4074 packages built. you were right, the stubbornness thing was enough.
