= Day 1 kernel module loading

[role="_abstract"]
Day 1 kernel module loading lets you insert kernel modules during Linux `systemd` initialization on {product-title}, before the standard KMM Day 2 loading and a complete initialization of a Linux (RHCOS) server. You can use the Machine Config Operator (MCO) when a module must load earlier than full node initialization.
