Description Harald Hoyer 2010-06-22 14:07:01 UTC

+++ This bug was initially created as a clone of Bug #589593 +++

Description of problem:
If I use system-config-network to change my ethernet connection to NOT be controlled by NetworkManager, then deactivate it, an empty /etc/modprobe.conf file is generated.  There shouldn't even be any code referring to this file anymore, AFAIK.  This may explain the mysterious empty modprobe.conf files that many people have seen, that cause warnings on boot.  The same thing happens on F12.

Version-Release number of selected component (if applicable):
system-config-network-1.6.0-2.fc14.noarch

How reproducible:
always

Steps to Reproduce:
1. Use s-c-n to edit ethernet connection so it's not controlled by NetworkManager.
2. Use s-c-n to deactivate the ethernet connection.
  
Actual results:
An empty /etc/modprobe.conf file is generated.

Right after installing F13 (AKA RC3) I used s-c-n to edit the ethernet connection to add a DHCP hostname.  Upon saving I had an empty /etc/modprobe.conf file.  It seems that just about any use of s-c-n to edit network settings triggers this.

Simplified procedure for reproducing: start s-c-n, then File/Save.  That's it.  The file /etc/modprobe.conf is immediately created.

But, if you close the applet with the x.
It doesn't create /etc/modprobe.conf

or s-c-n-tui
doesn't create it either.

Confirmed - if I run s-c-n-tui and immediately select "Save&Quit", it doesn't create the file.  Interesting.

Fixed upstream (commit f6d58b7).

In latest snap #12 there's only system-config-network-tui, not the GUI part.
