speaking on irc the reporter confirmed that if they curl the metadata
API the user data is correct

it my belief therefor that the issue is cause by not debootstraping the instance with  cloud-init clean
https://cloudinit.readthedocs.io/en/latest/topics/cli.html#clean
before taking the snapshot or a similar cloud-init config error.

it's likely that cloud-init is checking the instance id and first boot
files that it is creating and determining it does not need to redownload
the user-data form the metadata API.

setting this as invalid as this is out of scope of nova.

Title:
  user-data not getting updated when instance is rebuild using the
  snapshot taken from the same server

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Description
  ===========
  user-data not getting updated when the instance is rebuilt using the snapshot taken from the same instance

  Steps to reproduce
  ==================
  1. create an instance with the user-data
  openstack server create --image c2022d1d-5549-46f1-b220-810019ae7d5e --user-data user_data.txt 5b75696f-1f8a-45ea-ac8e-12b4988cb2d4 --os-compute-api-version=2.57
  2. login to instance and check user-data
  3. create a snapshot
  openstack server image create --name snapshot1 5b75696f-1f8a-45ea-ac8e-12b4988cb2d4
  4. rebuild the server with the snapshot and a different user-data
  openstack server rebuild --image c2022d1d-5549-46f1-b220-810019ae7d5e --user-data user_data_new.txt 5b75696f-1f8a-45ea-ac8e-12b4988cb2d4 --os-compute-api-version=2.57
  5. login to the instance and check user-data. the user-data passed during the rebuild is not present in /var/lib/cloud/instnace/user-data.txt. Its the old user-data which is passed during the instance creation

  Expected result
  ===============
  the user-data passed during the rebuild should be applied

  Actual result
  =============
  user-data passed during rebuid is not getting applied

  Environment
  ===========
  $ rpm -qa | grep nova
