[Bug 1947311] Re: Unexpected partition growth on first boot on impish for raspberry pi

[Noah]

Thanks for looking into this!

I was hoping to create an IoT package that was agnostic of which device
I deploy it on to, and cloud-init is great for this because it gives me
a universal API for provisioning that's supposed to work across all
ubuntu flavors and even other distros...

So for example, what might one day deployed to a Raspberry Pi, might be
tomorrow deployed to an Intel board, or a RiskV board... My user-data
script would pull in Docker and Docker would take care of the platform
agnostic fetching of images.. (eg, ARM or Intel)

With this in mind it would be great to fix cloud-init...

I've been going round in circles trying to find the package list where
cloud-initramfs-growroot has been added to... I tried looking in
https://github.com/snapcore/pi-gadget but I think that's only for
ubuntu-core and not the preinstalled server images..

Does anyone have ideas?

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
