Hi, I'm trying to create a custom initramfs to handle some things before switching root to my actual filesystem. I followed the docs and have been able to use INITRAMFS_IMAGE = "custom-image" and INITRAMFS_IMAGE_BUNDLE = "1" to generate a zImage for my ARM platform.
The custom-image.bb recipe is based on the core-image-minimal-initramfs recipe and is in a meta-layer that has another image recipe for the actual eMMC filesystem image. Both the eMMC image and initramfs bundle are created. In custom-image.bb, PACKAGE_INSTALL includes INITRAMFS_SCRIPTS which seem to be geared towards live-image things but that's not what I want. The image boots but hangs waiting for removable media. I figured out that /init is not pointing to systemd but the live-image script from recipes-core/initrdscripts. For testing I manually symlinked systemd to /init and the board boots but it wants a login password which was never created, I'm guessing its not inheriting debug-tweaks from my local.conf? So my question is, what is the correct way to create a minimal initramfs image along side the real recipe/image within a meta-layer? Does anyone have an example of doing this? Thanks, Matt.
