Subject: [PATCH] network: Only bring up wired network interfaces
|
|
|
18971c |
|
|
|
18971c |
The dracut network module is only supposed to be used for wired interfaces
|
|
|
18971c |
but if driver modules for wireless devices are wrongly copied, these will
|
|
|
18971c |
be loaded and the available interfaces brought up.
|
|
|
18971c |
|
|
|
18971c |
If the rd.neednet=1 command line parameter is used, dhclient will attempt
|
|
|
18971c |
to request an IP address for the interfaces and these requests will fail.
|
|
|
18971c |
|
|
|
18971c |
But other dracut modules that depend on the network to be settled, will
|
|
|
18971c |
have to wait for the DHCP requests to timeout. Which can be a lot of time
|
|
|
18971c |
since the dhclient default timeout value is 60 seconds.
|
|
|
18971c |
|
|
|
18971c |
Instead of trying to blacklist all possible kernel modules for wireless
|
|
|
18971c |
devices, only bring up network interfaces if these are for wired devices.
