# --- Guest kernel image (for Firecracker microVMs) ---
# Placed at /arcbox/kernel/vmlinux inside the guest VM.
#
# arm64 is the arcboxlabs/kernel `microvm` flavor (CORE-79): a dedicated
# minimal sandbox kernel (virtio-mmio only, no PCI/ACPI/EFI/netfilter)
# targeting kernel-entry -> PID 1 in the 200-300 ms class under nested
# virt. The version string keys the immutable CDN path
# (bin/vmlinux/{version}/{arch}/vmlinux), so rollback = revert this pin.
#
# x86_64 stays on the stock Firecracker CI kernel until an x86 microvm
# config lands (Firecracker x86_64 boots an ELF vmlinux and needs
# VIRTIO_MMIO_CMDLINE_DEVICES + kvmclock).
