hi,
after upgrading OS (Fedora 38 -> 39) on my router box, on boot systemd-sysctl is failing to write params to IPv6 interfaces
it appears systemd-sysctl is attempting to write config to an interface before it exists
This failure should usually be okay to ignore as there already is a udev rule which will trigger sysctl again (for net.* settings) whenever an interface appears, at any point (not just at boot).
But networkd's AcceptRA doesn't use the kernel's RA support – it's actually supposed to force accept_ra to zero and handle it in userspace, so if you're using networkd then you should be configuring this via networkd as well...
