All,
I realize it's late in the cycle but I just pushed an update to cloud-initramfs-tools: https://admin.fedoraproject.org/updates/cloud-initramfs-tools-0.20-2.fc20
The package contains fixes for:
1003153 - dracut growroot module leaves an empty directory around which breaks dracut 1016648 - ARM guest on x86_64 fails to boot, mount: special device /dev/vda3 does not exist 1009172 - dracut-modules-growroot does not enlarge /dev/mmcblk0
Karma is always welcome :-)
