@hiromotai7 new approach changes initrd's file name from emlinux-image-base-emlinux-bookworm-qemu-amd64-initrd.img to emlinux-initramfs-base-emlinux-bookworm-qemu-amd64-initrd.img. It breaks runqemu command. so, you need to update scripts/runqemu or keep ${IAMGE}-${DISTO}-${MACHINE}-initrd.img style file name. |

Thanks and sorry, I overlooked the impact on runqemu. I will open a new one just to add the initramfs recipe (commit 80b1bda only). |

Purpose
Added INITRD recipe for emlinux-image-base/weston.
Test
Comfirmed the following:
Test results
1. Confirming initrd.img creation
Add the following line to local.conf.
TMPDIR .= "-${BB_CURRENT_MC}"Run
bitbakeas follows to build:$ bitbake \ mc:qemu-arm64-bookworm:emlinux-image-base \ mc:qemu-arm64-trixie:emlinux-image-base \ mc:qemu-arm64-bookworm:emlinux-image-weston \ mc:qemu-arm64-trixie:emlinux-image-westonconfirmed that the initrd.img was generated and that it uses the name of the INITRD recipe.
emlinux-initramfs-base-emlinux-bookworm-qemu-arm64-initrd.img*
emlinux-initramfs-base-emlinux-trixie-qemu-arm64-initrd.img*
2. Compare the file list inside initrd.img
The original produces 4 initrd files.
Compared them respectively.
emlinux-bookworm
Ran the following commands for comparison.
No differences found.
emlinux-trixie
Ran the following commands for comparison.
No differences found.
Since the differences are identical to those in the two original files as below and no files were missing, I consider this to be acceptable.
