Subject: [PATCH] do 'ip route replace default' instead of 'add' |
|
|
|
When you define the gateway for an interface, dracut sets it up with: |
|
|
|
ip route add default via $gw dev $netif |
|
|
|
If a default route is already set (e.g. if you have multiple NICs), this |
|
will fail with the message "RTNETLINK answers: File exists". |
|
|
|
So, if your first NIC isn't usable as a default route |
|
|
|
Using "ip route replace default" instead allows ifup/dhclient-script to |
|
correctly change the default route to the new interface. |
