Bug 570256

I guess this was supposed to go to "distribution" ...

no, livecd-creator is the right place, that's the tool that creates the live image.

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

There should be a way to set this from the dhcp server (and it may already do that). But failing that livehost.localdomain is the correct name from /etc/hosts

In Fedora, the hostname comes from /etc/sysconfig/network, as shown in the attached screenshot.

There is nothing in the screenshot to identify it with Fedora, which is why I opened this bug. As a matter of user convenience and marketing, a Fedora Live CD should clearly identify itself as such.

Also, a dhcp server may not be configured (e.g. in QEMU) or misconfigured. For example, the Ubuntu Live CD has the annoying habit of configuring my router to return "ubuntu" for a reverse name lookup. After rebooting into F13:

[stephent@walnut ~]$ ip addr show dev eth0 | grep 'inet '
    inet 192.168.0.100/24 brd 192.168.0.255 scope global eth0
[stephent@walnut ~]$ host 192.168.0.100
100.0.168.192.in-addr.arpa domain name pointer ubuntu.lan.

AFAICT, Fedora Live does not get its hostname from a dhcp server. Whether or not to get the live hostname from a dhcp server could be configurable.

Kickstart has this option:

network
...
--hostname=
    Hostname for the installed system.

A possible fix for this bug is to add this to fedora-live-base.ks:

network --device=eth0 --hostname=FedoraLive

(The compose failed without "--device=eth0".)

This results in the line:
HOSTNAME=FedoraLive
being written to: 
/etc/sysconfig/network

Verified with F13:
$ sudo livecd-creator -c fedora-live-base.ks
$ qemu-kvm -m 512m -cdrom livecd-fedora-live-base-201010230904.iso

$ rpm -q livecd-tools
livecd-tools-033-3.fc13.x86_64

screenshot showing hostname in gdm login window

This screenshot shows a side-effect that removes info from the gdm login window:
Fedora release 14 (Laughlin)
gets reduced to:
FedoraLive

This appears to be normal gdm behavior.

If HOSTNAME is not set in /etc/sysconfig/network or it is set to "localhost.localdomain", gdm displays the string from /etc/fedora-release.

Verified with F14 installed in a VM.

If anything this should be implemented in the kickstarts, not in livecd-tools.

This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '13'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 13's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 13 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

(Please note: Our normal process is to give advanced warning of this
