Short circuit dracut?

[Justin Cattle]

If you're using PXELINUX to boot, you can use the ipappend option like this
in your pxe config:

ipappend 2

That will make it add this to the kernel comandline for the device it pxe'd
from:

BOOTIF=<hardware-address-of-boot-interface>

So dracut _should_ only use that interface and ignore the others.


If that's not working for you for some reason, another approach would be to
just change the timeouts.
This one is 60 seconds by default:

rd.net.timeout.iflink=10

..or even less if that will still work for the interface you do want
configured :)



Cheers,
Just
