# Crucible installer for Ubuntu/Debian. Installs Node + smartmontools +
# ipmitool, npm-installs @glassmkr/crucible, then delegates config/systemd
# setup to `glassmkr-crucible init` (Crucible 0.9.1+).
#
# Hosted at https://glassmkr.com/install.sh. Used by:
#
#   curl -sf https://glassmkr.com/install.sh | sudo bash -s -- --api-key <K>
#
# For standalone (no Dashboard) or telegram-enabled setups, see the README at
# https://github.com/glassmkr/crucible — hand-edit /etc/glassmkr/collector.yaml
# after the manual install.
