HELP needed: dracut 049: initqueue/online hook never triggered?

[LAHAYE Olivier]

Hi,
 
My module requires initqueue/online queue to be run. It works fine on CentOS-7, but fails on CentOS-8.1 (dracut-049-27.git20190906.el8_1.1.x86_64)
In fact it fails on all dracut version that have the 40network module split with 35network-legacy and 35network-manager.
 
On CentOS-8.1, by default, 40network uses 35network-manager which is fine, but then, I see no code that would run the initqueue/online hook in either 40network or 35network-manager (nor in 98systemd). Am I missing something?
 
My systemimager dracut module supports dracut from CentOS-6 (where I use udev to simulate online hook) to CentOS-8.0 which still run the online hook.
 
I’d like to avoid requiring 35network-legacy for multiple reasons:
• I don’t know how to require it only on CentOS-8.1 (make it optional)
• I don’t know how to finish boot using networkmanager if I start with legacy mode
• This legacy option won’t last forever…
I’d also like to avoid doing the same trick as I do on CentOS-6, playing with udev rules.
 
How do I have dracut do the following when using 45network-manager? (need initqueue is there and module module depends on network of course)
• source_hook initqueue/online $netif
 
I did look into 80anaconda module, that uses /tmp/net.*.did-setup in online_netdevs, but I wonder how this file can exists when 35network-manager is used? (when timeout occurs and drops me to a shell,  I see /tmp as almost empty while my network is up…)
 
My module source: https://github.com/finley/SystemImager/tree/SystemImager-NG/lib/dracut/modules.d/51systemimager
 
Many thanks for help on that as I’m stuck for now :-/

This might be fixed with commit 3dcaa97ca4dcfa8092252a22df62c60941e59ce3

You might want to try dracut-050-26.* from Fedora 31 or 32 or rawhide.
