grub-legacy-ec2 does not create /boot/grub on install

Binary package hint: cloud-init

recent uec-images builds have been failing on grub-legacy-ec2 installation like:

| Searching for GRUB installation directory ...
| No GRUB directory found. To create a template run 'mkdir /boot/grub' first.
| To install grub, install it manually or try the 'grub-install' command. ###
| Warning, grub-install is used to change your MBR. ###

I need to add /boot/grub to grub-legacy-ec2. it only worked previously because grub-pc (or grub-common) was getting installed and creating that dir for it.
