RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
Image Builder allows creating user and adding it to the wheel group which in turn allows the user to become root (sudo su -).
Currently there seems to be no way to allow a created user to become root without providing the user's password. Using automation tools such as Ansible is more feasible with setup and doesn't force users to do it for each system afterwards.
Version-Release number of selected component (if applicable):
RHEL 8.5

The password-less sudo for the default user in EC2 images is configured by cloud-init. AFAIK, we currently don't have any way to achieve this for custom users. There were some discussions about this in the past, but no real consensus or agreement. Nevertheless there is definitely a demand to allow this in composer / image-builder.
Since 8.8/9.2, this can be achieved via the custom files customization:
[[customizations.files]]
path = "/etc/sudoers.d/wheel-passwordless-sudo"
mode = "0400"
data = """
%wheel ALL=(ALL) NOPASSWD: ALL
"""
Marko, would that work for you?
