Thats unexpected. I thought it would fire every time, regardless if
the information changed or not. Cool stuff!

Good idea, I just tried that. My config now looks something like this:

option rapid_commit
option classless_static_routes
option interface_mtu

interface eth0
        static ip_address=192.168.0.7/24
        static routers=192.168.0.1
        static domain_name_servers=192.168.0.1 2a02:908:2:a::1 2a02:908:2:b::1
        dhcp6
        nooption ntp_servers, dhcp6_ntp_server, dhcp6_name_servers

Unfortunately my NTP service is still being restarted every 15 seconds.

I looked at the relevant packets and see, that dhcpcd is indeed not
requesting NTP or DNS information anymore - and the router is honoring
this. I am now even more puzzled, why the hook script keeps being
called.

As soon as I set "nohook timesyncd.conf" the restarts stop - so it's
definitely dhcpcd causing it. Any other ideas?
