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
