WIP: NM in the initrd

[cgwalters]

This seems not to run for me...I don't quite understand the
initqueue stuff, still debugging.

I've verified that we have the module code in the initrd, but it looks like the initqueue never executes /usr/lib/dracut/hooks/initqueue/settled/99-nm-run.sh (I added an echo statement to that code).

hm. Is there no further information here? Any logs?

What was the kernel command line?

If you don't even get 99-nm-run.sh to execute, then it's a dracut issue (or an issue in NM's dracut module).

since I'm having networking in the initrd troubles myself, I can try testing this out to see if I get any different results.

[cgwalters]

OK so...this is a bit obvious now, but entering emergency.target will kill other services - specifically it will kill dracut-initqueue.service. So to better replicate what's going on in the normal case, be sure to at least systemctl start dracut-initqueue.

rd.neednet ip=dhcp are the relevant bits.

I can paste the full journal if you want (it's also easy to do a FCOS build from this patch) but AFAICS there's nothing there of use because:

Right. That's as far as I got - it's not clear to me why that hook isn't being executed. I don't understand the initqueue really to be honest.

As best I can tell what's happening is /usr/bin/dracut-initqueue is calling check_finished which looks for files in $hookdir/initqueue/finished/ - and since nothing is there, we exit before trying any of the other hooks.

It seems like other dracut initrd code is dropping files there, but the NM initrd code isn't.

Was this NM initrd code ever tested? If so, where?

Hi, for the dracut problem I have filed an issue that is related to your problem sometime ago, maybe we can discuss there:
See dracutdevs/dracut#694

[cgwalters]

@ryncsn Thank you, that looks exactly like the bug!

Hopefully this'll be unblocked with the next dracut build :)

[dustymabe]

Now that dracutdevs/dracut#694 is fixed I'm picking this up and running with it. I'm going to close this out and open a new PR with more fixes in it.
