Comment # 1 on bug 1188915 from Joerg Roedel

The issue is likely here in /usr/bin/dracut:

| # source our config file
| if [[ -f $conffile ]]; then
|     check_conf_file "$conffile"
|     # shellcheck disable=SC1090
|     . "$conffile"
| fi
|
| # source our config dir
| for f in $(dropindirs_sort ".conf" "$confdir"
"$dracutbasedir/dracut.conf.d"); do
|     check_conf_file "$f"
|     # shellcheck disable=SC1090
|     [[ -e $f ]] && . "$f"
| done

The config file is sourced before the config directories. The directory which
constains 01-dist.conf is even sourced last, so there is no way to overwrite
the hostonly default set by the package.

I think the dist-defaults belong into /etc/dracut.conf so that users can
replace/update them.
