The same holds for other values I think. I once hit the same problem
with the IPv6PrivacyExtensions setting. I enabled it via sysctl and
wondered why it was disabled for one device, which I had configured
using systemd-networkd.
Although this is clearly documented in the man page I think it would be
less surprising behavior to generally default to kernel for such
configuration items. Is there a specific reason against that?
Cheers,
Michael
