# copy renderers copy_exec /usr/lib/@DEB_HOST_MULTIARCH@/plymouth/renderers/frame-buffer.so copy_exec /usr/lib/@DEB_HOST_MULTIARCH@/plymouth/renderers/drm.so
Also do you use disk encryption? because the content of the initrd should only matter in that scenario since otherwise plytmouth should have access to the /usr content
