cloud-initramfs-copymods 0.47ubuntu1 (amd64 binary) in ubuntu groovy

 When booting with an external-to-root kernel and initramfs, you need
 to ensure that /lib/modules contains any necessary modules not already
 loaded.
 .
 This package arranges for the modules in the initramfs to be placed
 into /lib/modules after the switchroot is done.
