# Customize the initramfs package

To update the initramfs package contents, modify the `PACKAGE_INSTALL` list in
`meta-qcom/recipes-kernel/images/initramfs-qcom-image.bb`:

```text theme={null}
DESCRIPTION = "Ramdisk image for pivoting into rootfs"

PACKAGE_INSTALL += " \
    base-passwd \
    initramfs-module-copy-modules \
    initramfs-module-rootfs \
    initramfs-module-udev \
    ${VIRTUAL-RUNTIME_base-utils} \
    ${MACHINE_ESSENTIAL_EXTRA_RDEPENDS} \
    ${ROOTFS_BOOTSTRAP_INSTALL} \
    "
```

After modifying `PACKAGE_INSTALL`, rebuild the full image to apply the change:

```bash theme={null}
bitbake qcom-multimedia-image
```
