• Setting Linux kernel parameters with sysctl: runtime changes versus /etc/sysctl.d

  sysctl -w changes a kernel parameter until the next reboot; making it persistent means dropping a file into /etc/sysctl.d/ and understanding the load order across /usr/lib, /etc and /run. sysctl --system applies every configured file and reports which one wins on a conflict.
