[Bug 1267225] Re: initramfs in cloud-images does not contain crypt modules

[Scott Moser]

This looks like a build-time bug in both overlayroot and crypt-setup.
 overlayroot/hooks/overlayroot does:
    egrep -qswo "aes" /proc/cpuinfo && manual_add_modules aesni_intel || true

And cryptsetup's /usr/share/initramfs-tools/hooks/cryptroot does:
                # Load hardware aes module
                if cpu_has_aesni; then
                        echo aesni
                fi
and
cpu_has_aesni() {
        return $(grep -q "^flags\s*:\s*.*aes" /proc/cpuinfo)
}


Seems like both of these should not be dynamic based on host cpu support, but constant built in on module availability in the kernel.
