If it was NetworkManager, this might have been the causing commit: http://lists.suse.com/archive/opensuse-commit/2011-01/msg00551.html

AFAS it isn't the above commit. I guess, the NM on 11.4 makes this sort of modifications. But as long as NM is running and updates the /etc/hosts correctly on all IP changes, it basically works. I guess, it is a workaround against broken dns server or something like this. Enabling something like this is _very_ questionable, because it breaks correctly configured networks. e.g. in my case, it breaks my IPv6 setup. I didn't tested it, just guess: when you switch from NM to ifup or also when kiwi copies /etc/hosts from live-cd to the running system, the file contains these modifications, because NM does not cleanup them properly. (In reply to comment #2)

the opensuse live cd uses network manager and the bug is that _if_ he enables the option manually, it doesn't work.

This is not really correct. The Live-CD / installation system may use NM, but the installed system when booting from the ISO and choosing "Installation" (in grub) AFAIS makes use of ifup by default. I've installed using yast2 defaults and Bernhard too.

Created an attachment (id=410469) --> (http://bugzilla.novell.com/attachment.cgi?id=410469) [details] bash -x ifup eth0

LiveCD installs fail to set hostname

Steps To Reproduce: install LiveCD Build1025 or later echo susetest.zq1.de > /etc/HOSTNAME hostname susetest alternatively use yast2 lan to set hostname. have "Change Hostname via DHCP" enabled.

ifdown eth0 ifup eth0 hostname

Actual Results: prints "linux"

Expected Results should print "susetest"

Reproducible: Always

I've tested this issue in the RC1, after reboot the hostname show the correct name. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Author: Dan Williams <dcbw@redhat.com> Date: Fri Dec 17 09:22:11 2010 -0600 policy: stop touching /etc/hosts Handling of /etc/hosts is highly site- and admin- specific in many more complex cases, and it's exceedingly hard and error- prone for NetworkManager to handle all those cases. So remove this functionality entirely. That's not a big loss, as it turns out there's a much more elegant solution. The only requirement is that the machine's hostname map back to an IP address owned by the machine. That requirement can be satisifed by nss-myhostname or even possibly the distro's installer. If the user does not want nss-myhostname then it can be uninstalled. Distros should use a "recommends" feature in their packaging system so that the NetworkManager package does *not* have a hard requirement on nss-myhostname. Thus everyone is happy; things Just Work when nss-myhostname is installed, but more advanced users can uninstall it and customize /etc/hosts as they wish. Another alternative is a dispatcher script that listents for the 'hostname' event, and updates /etc/hosts according to the administrator's preference. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

commit 39eed50e470d6f41222e40ce0276b898e8c84dc4 I view the soucecode in the upstream, and found no touching the /etc/hosts now.

Good.

When it does not touch /etc/hosts any more, please submit for RC2. Thanks! BTW: nss-myhostname sounds interessting. I think, we have to take closer look at it.
