that is another option, to remove cloud-initramfs-growroot from the image/initrd.
The problem with that is that you're then relying on cloud-init to grow the rootfs, and if you
disable cloud-init you don't get the grow.

I'm not exactly sure what the purpose of these images is.

  Unexpected partition growth on first boot on impish for raspberry pi

Bug description:
  Hi,

  On Raspberry Pi since Impish, the partition always grows even if I set
  the following in user-data of cloud-init.

  growpart:
    mode: off
    devices: ['/']

  I have tested this on 21.04, and it works, but is broken on 21.10.
  (partition always grows)

  I've also tested this in KVM on amd64, and it works (partition does
  NOT grow).

  This is a problem for me because I am using runcmd in cloud init to
  migrate my drive to LVM/LUKS, and the partitioning step fails because
  the drive is already full.

  Cheers,
  Noah
