#
# Eldric AI OS — one-liner bootstrap
#
# Usage:
#   curl -fsSL https://repo.eldric.ai/install-eldric.sh | sudo bash
#
# With options (you must use -s -- to separate bash args from script args):
#   curl -fsSL https://repo.eldric.ai/install-eldric.sh | \
#       sudo bash -s -- --license /tmp/license.json --admin-email me@example.com
#
# Flow:
#   1. Check root + supported distro
#   2. Add the dnf repo via setup-dnf-repo.sh (inline if not yet on disk)
#   3. dnf install -y eldric-aios
#   4. systemctl enable --now eldric-aios
#   5. Hand off remaining args to `eldric setup` (C++ post-install logic:
#      health wait, license activation, admin setup, summary)
#
# Refuses if /var/lib/eldric exists — that's an upgrade case, route via
# `eldric upgrade` (not yet implemented; today it's still manual dnf upgrade).
