Situation

The symbolic link /etc/sysctl.d/99-sysctl.conf to /etc/sysctl.conf has vanished.

Resolution

No action required.

Cause

With SLES 12 SP4 onwards the symbolic link /etc/sysctl.d/99-sysctl.conf to /etc/sysctl.conf has been removed.

Since the sysctl commandline tool reads /etc/sysctl.conf directly, the symbolic link was just needed for /usr/lib/systemd/systemd-sysctl.
With the systemd package shipping the link /usr/lib/sysctl.d/99-sysctl.conf to /etc/sysctl.conf, the link in /etc/sysctl.d/ becomes obsolete.

Additional Information
