# vpdmn-initramfs-create_1.0.bb
# ===========================================================================
# Builds QEMU boot blobs for vpdmn (Podman CLI)
# ===========================================================================
#
# This recipe packages the boot blobs for vpdmn:
# - A tiny initramfs with just busybox for switch_root
# - The rootfs.img squashfs image with Podman (built via multiconfig)
# - The kernel
#
# Boot flow:
# QEMU boots kernel + tiny initramfs
# -> preinit mounts rootfs.img from /dev/vda
# -> switch_root into rootfs.img
# -> vpdmn-init.sh runs with a real root filesystem
# -> Podman executes container commands
#
# ===========================================================================
# BUILD INSTRUCTIONS
# ===========================================================================
#
# For aarch64 (multiconfig dependency is automatic):
# MACHINE=qemuarm64 bitbake vpdmn-initramfs-create
#
# For x86_64:
# MACHINE=qemux86-64 bitbake vpdmn-initramfs-create
#
# Blobs are deployed to: tmp-vruntime-*/deploy/images/${MACHINE}/vpdmn/
#
# To build the complete standalone tarball (recommended):
# MACHINE=qemux86-64 bitbake vcontainer-native -c create_tarball
#
# ===========================================================================
