Description of problem:
IBM T30 with wire on eth0 and internal wireless ethernet on eth1. /etc/sysconfig/network-scripts/ifcfg-eth1 has ONBOOT=no. 
On boot udev calls hotplug which calls:
  /sbin/ifup /etc/sysconfig/network-scripts/ifcfg-eth1
With no options and thus it comes up on boot when it should not.

Also happens on RHEL 4 U2 on the same machine.

Version-Release number of selected component (if applicable):
hotplug-2004_09_23-7  udev-058-1.0.FC4.1

How reproducible:
Always

Steps to Reproduce:
1. Boot the machine with stock install and internal wireless
2. Have ifcfg-eth1 with ONBOOT=no
3. netstat -nr
  

Actual Results:  eth1 is up and has the primary gateway.

Expected Results:  eth1 should be down.

Additional info:

If you edit /sbin/ifup and insert the line:

 sleep 5;

Before:

  if [ "foo$2" = "fooboot" ] && [ "${ONBOOT}" = "no" -o "${ONBOOT}" = "NO" ]

It prevents the problem.
