+Disable cloud-init's resizefs module
+------------------------------------
+
+The cloud-init resizefs module can be extremely slow and will also
+unwittingly create a root filesystem that cannot be booted by grub if
+the underlying partition is too big. This removes it from cloud.cfg,
+putting the onus for resizing on the user post-boot.
