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.
The *netconsole* utility now launches correctly
Previously, if `nameserver` address lines were not present in the `/etc/resolv.conf` file, launching *netconsole* sometimes resulted in an error and *netconsole* did not start. The _initscripts_ package has been updated, and *netconsole* now starts correctly in this situation.

Patch file, replaces command 'hosts' with 'getent'
Description of problem:
netconsole script fails if the syslog address is not available via a DNS server, this prevents netconsole to work with hosts that have not access to a DNS server and have the hostsnames hardcoded in /etc/hosts.
This applies for RHEL7 releases too
Version-Release number of selected component (if applicable):
Up to initscripts-9.49.24-1.el7
How reproducible:
Always
Steps to Reproduce:
1. Remove the nameserver lines from /etc/resolv.conf
2. add the syslog server IP and name to /etc/hosts
3. run the netconsole.
4. despite we can resolve the syslog server name it will fail with an missleading message:
"Server address not specified in /etc/sysconfig/netconsole'
Actual results:
"Server address not specified in /etc/sysconfig/netconsole'
Expected results:
Starts normally
Additional info:
A patch for this is provided
