Hello,
the update to trixie caused the /etc/sysctl.conf file to be ignored. systemd-sysctl reads kernel paramters from /etc/sysctl.conf.d/*. On bookworm there was a symlink /etc/sysctl.d/99-sysctl.conf to /etc/sysctl.conf. This symlink got dropped during the upgrade causing the file to be ignored. As kernel parameters in sysctl.conf are very core to the system and them not getting applied can lead to breakage and security issues, I think this should be documented in the release notes. 

Thank you,
Basilikum
