@bam80 can you please explain what is wanted? I don't remember much, but at the link you posted I see a description that seems pretty detailed. Are you asking me to add this to the dracut repo?

[bam80]

Yes, I occasionally found the doc in Anaconda repo and extended it with the details, but that belongs to dracut in general, so we probably need to have it somewhere in dracut docs, too.
