Description Alex Harpin 2014-07-26 10:11:09 UTC
Description of problem:

When a bridged interface is configured to start up on boot via the
kernel command line options, the resulting ifcfg files produced by
the 45ifcfg dracut module are incorrect.  Atlthough the interface is
brought up correctly on start up, and functions as expected, when the
configuration file is imported into the booted system it prevents the
bridged interface from being successfully restarted.

This patch rewrites the section of 45ifcfg responsible for the creation
of the required ifcfg files.

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

Fedora 20 x86_64; Dracut 037-11.git20140402

How reproducible:

Steps to Reproduce:
1. Setup bonded interface in /boot/grub2/grub.cfg (parameters below)
2. Reboot

Actual results:

The bridged interface is brought up correctly during boot up, but the configuration files produced by the 45ifcfg dracut module (ifcfg-br0 and ifcfg-enp5s0 in this particular case) are incorrect.  Once these files are imported into the running system, a subsequent restart pf the bridge interface fails.

Expected results:

The bridge interface works during the initial boot up sequence and subsequently when the system is up and running.

Additional info:

Relevant grub kernel parameters: bridge=br0:enp5s0 ip=br0:dhcp

Comment 5 Fedora End Of Life 2015-05-29 12:28:35 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. 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bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora  'version'
of '20'.

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.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 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, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

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.

Comment 6 Fedora End Of Life 2015-06-29 21:46:06 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
