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 Brian Smith 2022-05-04 19:22:50 UTC 
Description of problem:
The firewall system role README.md file has several examples with syntax similar to this:

service: [ 'tftp', 'ftp' ]

From what I understand this syntax is deprecated and the recommended syntax is:

service: [tftp, ftp]

Version-Release number of selected component (if applicable):  RHEL 8.6 / 9.0


How reproducible:
Every time

Steps to Reproduce:
1. cat /usr/share/doc/rhel-system-roles/firewall/README.md

To clarify:

service: [tftp, ftp]

Is preferred for very short lists as opposed to

service:
  - tftp
  - ftp

which is also correct but much more verbose.

note that '[tftp, ftp]' is a string, not a list

Also note that [tftp, ftp] is preferred over ['tftp', 'ftp'] since in YAML tftp and ftp are unambiguously string values.

However, port: ['443/tcp', '443/udp']

the values should be quoted as they begin with a number - quoting the values explicitly makes them strings so there is no ambiguity.
