I was able to build with osbuild but during the boot it exploded.

You should maybe change this:

conf_read(&conf, "/etc/initoverlayfs.conf");

to this:

conf_read(&conf, "/etc/local/initoverlayfs.conf");

I haven't tested or anything though... Maybe there's a couple of things in different places...

This has also pointed out that we probably need more logging inside conf_read. Like log when fopen fails.

Oh wait scratch that though maybe not because you copied to:

/etc/initoverlayfs.conf

In initrd...

Anyway, it looks like bootfs variable is empty, that comes from /etc/initoverlayfs.conf file

It's the variable that contains bootfs details, so it knows which partition to mount for /boot

Have no problem making this /usr/local/etc everywhere if it works, even in initrd

Sure, I am doing some tests here, I will update here as soon I get something working.

We should be very close here, we just need to produce more output in osbuild to see where this is falling over. Could you paste the full output of the dracut section, including the names of the osbuild stages that are running dracut @dougsland ?

Still failing for reach /usr/local/etc/ using inst_simple /usr/local/etc/initoverlayfs.conf /etc/initoverlayfs.conf or inst_dir /boot /initrofs /overlay /overlay/upper /overlay/work /usr /usr/local/ /usr/local/etc/

However, dracut output seems more friendly when using /initoverlayfs.conf:
