Description Bill Nottingham 2011-02-02 21:57:06 UTC
+++ This bug was initially created as a clone of Bug #673238 +++

Description of problem:

After a fresh @minimal install of rawhide, the udev rules file (/etc/udev/rules.d/70-persistent-net.rules) created by anaconda is incorrect.

Apparently it should have KERNEL=="eth0", instead of KERNEL=="pci2*".  See below for additional details.

Version-Release number of selected component (if applicable):
* anaconda-15.18-1.fc15

How reproducible:

Steps to Reproduce:
1. Boot rawhide boot.iso (see for link https://fedoraproject.org/wiki/Test_Day:2011-01-27_Network_Device_Naming_With_Biosdevname)
2. At the time of this bug, using an updates.img is required (see test day link above)
3. Perform a @minimal install (which currently does *not* install biosdevname)
4. Complete installation.  Before reboot, manually create a dracut initramfs to work around bug#673192
Actual results:

After booting into system ... the system is confused by the name of the iface.  It uses eth0 and pci2#1.

For example ...

# ls /sys/class/net/
eth0  lo

# ls /etc/sysconfig/network-scripts/ifcfg-*

Expected results:

pci2#1 should be used in all cases

Additional info:

1) Further investigation shows that the package 'biosdevname' is *not* installed
2) Because biosdevname is *not* installed, and because the udev rules (created by anaconda I think) are not correct (so I'm told ... I don't fully understand the rules format) (KERNEL=="pci2#*"), it defaults to eth0.

$ cat /etc/udev/rules.d/70-persistent-net.rules 

# This file was automatically generated by the /lib/udev/write_net_rules
# program run by the persistent-net-generator.rules rules file.
# You can modify it, as long as you keep each rule on a single line.

# Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rule written by anaconda)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="52:54:00:a4:29:75", ATTR{type}=="1", KERNEL=="pci2#*", NAME="pci2#1"
3) # biosdevname -d

biosdevname does need to be always installed, and needs to be in Kickstart or minimal configs too.

--- Additional comment from dcantrell@redhat.com on 2011-02-02 09:23:21 EST ---

comps needs to add biosdevname to the minimal group.

--- Additional comment from notting@redhat.com on 2011-02-02 14:02:28 EST ---

Done, but according to upstream, we shouldn't be writing persistent rules for biosdevname-handled interfaces. Patch forthcoming.

Comment 1 David Cantrell 2011-02-03 02:53:18 UTC
Patch is already on the list for this:


Comment 2 RHEL Program Management 2011-02-03 03:10:18 UTC
This request was evaluated by Red Hat Product Management for inclusion
in a Red Hat Enterprise Linux maintenance release. Product Management has 
requested further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed 
products. This request is not yet committed for inclusion in an Update release.

Comment 5 Alexander Todorov 2011-03-09 13:04:23 UTC
With the 0308.n.1 tree biosdevname wasn't installed with the minimal group. "eth" was used to identify the device name and the 70-persistent-net.rules was not generated by anaconda and was correct.
