Description Jesús Pérez Martínez 2023-04-14 14:56:22 UTC

Description of problem:
Currently creating a template with a user and group with the same name, and equal UID and GID is not possible.

Version-Release number of selected component (if applicable):
osbuild-composer-62.1-3.el9_1.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Create a template and define a user with a custom UID and GID. UID and GID must be equal:

[[customizations.user]]
name = "test"
description = "Test Account"
home = "/home/test"
shell = "/usr/bin/bash"
key = ""
uid = 802
gid = 802

2. Use [[customizations.group]] to create the group with the GID we set previously on [[customizations.user]] and the same name as the user:

[[customizations.group]]
name = "test"
gid = 802

3. Try to build the image.

Actual results:
The image build job fails with "useradd: group '802' does not exist"

Expected results:
The image builds correctly, with the user test (UID 802) and the group test (GID 802)
