I would prefer the !BR2_INIT_SYSTEMD as I believe iwd needs
an service of the running systemd (or an alternative implementation)
and not a feature/library of the systemd package (only runtime not
a compile time dependency)...

On re-builds the common IWD_INSTALL_CONFIG_FILE (copy plain main.conf will
be executed first, so no problem...

Does not work, gives:
sed: -e expression #1, char 46: missing command
And did not figure out what would be the right sed exprecssion (the leading $
seems to be wrong, but without another error occures)...

Nice shortcut, but misses the enable-the-one-option-for-systemd and
enable-the-other-option-for-all-other-init-systems...

Nice, but see downside above...
Thanks for review,
