# Ongoing rework (e.g. PR #2652) arising from ansible.posix collection changes:
- name: Use 'sysctl' to set 5 network/kernel settings, turning off IPv6 if possible
- name: "Use 'sysctl' to set 'kernel.core_uses_pid: 1' + 4 network settings in /etc/sysctl.conf -- e.g. disabling IPv6 (this might be overkill, as IPv6 should really only be disabled on the LAN side, i.e. br0)"
sysctl: # Places these settings in /etc/sysctl.conf, to survive reboot
