services.earlyoom.killHook

An absolute path to an executable to be run for each process killed. Some environment variables are available, see README and the man page for details.

WARNING: earlyoom is running in a sandbox with ProtectSystem="strict" by default, so filesystem write is also prohibited for the hook. If you want to change these protection rules, override the systemd service via systemd.services.earlyoom.serviceConfig.ProtectSystem.

Type

Default

Example

pkgs.writeShellScript "earlyoom-kill-hook" ''
