# ── RAM-disk QEMU boot ──────────────────────────────────────────────────
# Copies harddrive.img (or live ISO) into tmpfs before booting QEMU.
# Eliminates all disk I/O during OS runtime. Requires sufficient RAM:
#   QEMU_MEM (default 2048 MiB) + image size + 512 MiB overhead.
#
# Usage:
#   make qemu-ram                      # Boot from RAM (default config)
#   make qemu-ram CONFIG_NAME=redbear-full QEMU_MEM=12288
#   make qemu-ram live=yes             # RAM-disk live ISO boot
#
# The tmpfs is mounted at /tmp/redbear-ram-<uid>/ and auto-cleaned on exit.
