[arch-general] IPv6 fast address rotation with systemd-networkd 249rc2-1 in [testing]

Hi I'm having an issue with IPv6 connectivity since systemd-networkd 249rc2-1 from [testing]. I noticed SSH sessions (all IPv6) locking up every few minutes, and after some digging it turns out to be due to very fast IPv6 temporary address rotation, making any long-lived SSH session impossible. I'm using systemd-network for network configuration, and downgrading systemd to 248 and rebooting fixed the issue. After upgrading again, but not rebooting, just restarting systemd-networkd introduces the issue again. So it's clearly a systemd-networkd introduced issue. Anyone else seeing this? Geert
