[PATCH 3/3] allow network setup without netroot

[Will Woods]

Currently, network configuration arguments are ignored *unless* the root
device is a network device. But there are some cases where you might
want to set up the network even though you have a non-network root
device (e.g. to fetch updates from the network for a livecd image).

With this patch you can set "netroot=no", which will cause dracut to set
up the network according to your other boot arguments but not attempt to
set up a network root device.

..on second thought, this might not be the best way to handle this use
case. There's a bunch of other network setup stuff that happens
afterward in 'netroot', and we probably will want that for whatever
network stuff is happening instead of mounting root.

Maybe a 'dummyroot' netroot "handler" that doesn't do anything would be
better - that way anything that wants to trigger when the network is up
can just add items to the 'netroot' hook, and they'll run like normal
netroot hooks.

If anyone's got opinions on the matter, let me know - otherwise I'll
probably have a different version of this patch in a day or two. Skip it
for now.

I have sent a patch for manually ifup nic, which deal with this problem
 and also be useful when we use initrd as minimal recovery system.

see:
http://www.spinics.net/lists/linux-initramfs/msg02205.html

Yes, dummy netroot is a reasonable idea for automatically bring up
network, but I still do not want to lose the manual setup option.
I'd like to have both :)

Right - they're different problems with different solutions.

I'm looking into automatic network setup for non-netroot systems because
I'm trying to replicate a lot of the stuff that anaconda (the RH/Fedora
installer) used to do in its own custom initramfs system - like fetching
updates, driver disks, and the runtime root filesystem image from the
network.

Fetching the runtime image is already done - see modules.d/90livenet.

I've got nearly-finished code for the "rd.live.updates" argument,
which would let us push out (or test) bugfixes for LiveCDs after
they've been burned/released. (Which would be nice!)

Driver disks I'm still working on, but that'll be coming soon too.

Anyway, that stuff is all pretty separate from what it sounds like you're
working on - so I think there's definitely room for both. No worries.

Hi,

Thanks for explanation.

For kdump automatic network setup for non-netroot systems is also a good
solution, I'd like to see the feature doesn't depend on "livenet"
