bootimg generator for Halium ports

mka halium-boot

Sometimes you might want to make changes to the initramfs locally, such as to fix a device-specific quirk. To do this, follow these instructions:

1. Download the current initramfs from initramfs-tools-halium releases
2. Create a working directory for the files: mkdir halium-initramfs
3. Extract the image: zcat initrd.img-touch-armhf | cpio -D halium-initramfs -idmv
4. Make your edits to the files in halium-initramfs/. The file that you will probably want to edit is scripts/halium
5. Repack the image: cd halium-initramfs/ && find . | cpio -H newc -o | gzip -9 > ../initramfs.gz && cd ..
6. Place the initramfs.gz file you just created in your device tree. This is the directory in device/[manufacturer]/[board] for your device.
7. Add BOARD_USE_LOCAL_INITRD := true to the end of your BoardConfig.mk.
8. Set up your environment and build with mka halium-boot

Don't forget to remove the initramfs.gz file and remove BOARD_USE_LOCAL_INITRD := true after you have proposed your changes to initramfs-tools-halium. This ensures that your port is in line with other Halium ports.

If you'd prefer to rebuild a whole initramfs from source, see the build instructions in initramfs-tools-halium. Once you've built the image, rename it to initramfs.gz and follow the instructions from step 6 above.
