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:

a kickstart install fails with Unknown Command and states the install exited abnormally due to an old command passed (kickstart file reused)

see screenshot for exact failure

Version-Release number of selected component (if applicable):

6.0 GA
anaconda 13.21.82

How reproducible:

use old commands like langsupport in kick start file and start the install. 

Steps to Reproduce:
1. see above
2.
3.
  
Actual results:

see attached screnshot from console

Expected results:

a softer message, like "ignoring unknown command" but proceeding with the install


Additional info:

This is how kickstart works - you use a command that no longer exists, and kickstart halts with an error message.  It's just like any other language in this respect.  langsupport was deprecated in time for RHEL5 which means you've had a warning getting logged since then.

It's also worth pointing out that you can use the ksvalidator command in the pykickstart package to check your kickstart config file before running it through anaconda, just to make sure you're not using anything that's invalid.
