# Wrapper around nixos-rebuild and deploy-rs for the three hosts.
#
# Usage:
#   ./deploy.sh                 # nixos-rebuild boot on current host (mreow/yarn)
#   ./deploy.sh switch          # apply immediately on current host
#   ./deploy.sh test            # apply without adding boot entry
#   ./deploy.sh build           # build only, no activation
#   ./deploy.sh muffin          # build + deploy to muffin via deploy-rs
#
# muffin cannot be rebuilt locally from another host — this script only issues
# the remote deploy via deploy-rs when explicitly named.
