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:
Updating systemd package add myhostname to the hosts line of /etc/nsswith.conf by postinstall scriptlet.
I think this script should run only time to install, not run time to upgrade.
Version-Release number of selected component (if applicable):
systemd-219-26.el7.x86_64
How reproducible:
Updating systemd package
Steps to Reproduce:
1. grep '^hosts:' /etc/nsswitch.conf
hosts: files dns
2. yum update systemd
Actual results:
# grep '^hosts:' /etc/nsswitch.conf
hosts: files dns myhostname
Expected results:
# grep '^hosts:' /etc/nsswitch.conf
hosts: files dns
Additional info:
Some users would not like to use nss-myhostname.
These users delete myhostname from the hosts line of /etc/nsswith.conf.
Updating systemd package break this settings.
