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 daniel 2015-12-11 16:57:29 UTC
Description of problem:
System is not valuing DHCP hostname when installed using a different DHCP (IP|name) as the DHCP name gotten during installation is included in initramfs image.

Version-Release number of selected component (if applicable): RHEL 7.1

How reproducible:

Steps to Reproduce:
1. Install Server via kickstart or from CD connected to DHCP server with network enabled to get hostname/ip from DHCP
2. Move server to different DHCP or ensure otherwise it get's a different name from DHCP
3. Boot Server and check hostname, still the one from initial installation is used

Actual results:

Still hostname set by DHCP during installation is used

Expected results:

Hostname from current DHCP should be used 

Additional info:

having a look at the initramfs generated during install shows the name which was assigned by DHCP:

# lsinitrd -f /etc/hostname initramfs-3.10.0-327.el7.x86_64kdump.img 

so current DHCP offered hostname is ignore as it has already a hostname assigned. Anaconda should not populate /etc/hostname during istallation so this does not get included in initramfs image and new hostname offered by DHCP is used
