Comparing an old and new initramfs I see a tonne more files across a
great many dirs:

 * usr/lib/firmware
 * usr/lib/modules/$VER/kernel/arch/x86/crypto
 * usr/lib/modules/$VER/kernel/drivers/char/tpm
 * usr/lib/modules/$VER/kernel/drivers/crypto
 * usr/lib/modules/$VER/kernel/drivers/net
 * usr/lib/modules/$VER/kernel/fs
 * usr/lib/modules/$VER/kernel/net

With regards,
Daniel
