      Given a system with checkpoint protecting in-memory profile in NetworkManager,
      When user converted these in-memory profiles into persistent and do rollback,
      Then those persistent profiles should be removed and replaced with original in-memory profile.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Integration tests are written and pass
      • The fix is part of a downstream build attached to an errata
      • The fix is backported into RHEL-9.2 (OCP 4.16 initially will use RHEL 9.2.z)

       

      AC and QE test alignment:

      The snapshot_rollback_in_memory test has been added and is testing that in-memory connection is not persistent after rollback: https://gitlab.freedesktop.org/NetworkManager/NetworkManager-ci/-/merge_requests/1692

      Steps to reproduce

      #!/bin/bash -x

echo '---
interfaces:
- name: dummy1
  type: dummy
' | nmstatectl set - --memory-only

echo "Before creating checkpoint"
PAGER="" nmcli -f 'filename,name,uuid' c show

echo '
---
interfaces:
- name: dummy1
  type: dummy
' | nmstatectl set - --no-commit

nmstatectl rollback

echo "After checkpoint rollback"
PAGER="" nmcli -f 'filename,name,uuid' c show

      Expected results

      The `dummy1` profile restored back to in-memory (stored in /run/NetworkManager/system-connections folder)

      Actual results

      The `dummy1` profile is stored as persistent profile in /etc/NetworkManager/ssytem-connections folder
