Description Don Hoover 2010-04-27 03:22:03 UTC

Description of problem:
Apparently the /tmp/netinfo file is no longer created by anaconda.  This was a widely documented place since RH7.x days to get the current network settings during %pre/%post scripts in kickstarts.  I see from the anaconda dev list that this was removed sometime during FC12 without much discussion.  

This should be documented in the Release Notes probably since it was such as very popular thing to do during kickstart scripts.  

It was a handy way to copy the network settings obtained via DHCP into your kickstart via a %include.


Version-Release number of selected component (if applicable):
EL6 Beta 1

How reproducible:
/tmp/netinfo file no longer created by anaconda

Steps to Reproduce:
1. %pre script in kickstart
2. cat /tmp/netinfo
3. file does not exist
  
Actual results:
File would exist and have current network settings in an easily parseable format.

Expected results:


Additional info:

Is there a replacement for this functionality outside of just replacing the parsing of the /tmp/netinfo file with a bunch more code to gather it manually via ifconfig etc?  

Otherwise this should be a good note to put into the EL6 release notes.

Comment 2 RHEL Program Management 2010-04-27 04:25:22 UTC

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.

Comment 3 David Cantrell 2010-04-27 13:48:58 UTC

This is not a bug, but something we need to note in the release notes.

Ryan, what state should I leave the bug in since this is just a release notes issue?  What flags should I have set?

Kickstarts users will find that /tmp/netinfo is no longer available under RHEL 6.0.  Anaconda is now using NetworkManager for network interface configuration.  Rather than looking at /tmp/netinfo for network settings used during installation, users can source the ifcfg files found in /etc/sysconfig/network-scripts, just like on a running system.

Comment 9 Ruediger Landmann 2010-06-23 06:29:04 UTC

Added as an admonition in "32.1. What are Kickstart Installations?" from build 0-67 onwards:

"Note — /tmp/netinfo no longer used
Anaconda now configures network interfaces with NetworkManager. Consequently, kickstart users that referenced the network settings located in /tmp/netinfo in previous versions of Red hat Enterprise Linux must now source the ifcfg files in /etc/sysconfig/network-scripts. "

(this admonition follows the description of /tmp as the location to which scriptlets and log files are saved)

Comment 10 Michael Doyle 2010-07-05 00:07:01 UTC

Verified it is in Red_Hat_Enterprise_Linux-Installation_Guide-6-en-US-0-74.

Comment 11 releng-rhel@redhat.com 2010-11-11 15:33:42 UTC

Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
