💖 RCTL(4) — the resource limits girlies' era 💖

okay so bestie, welcome to the rctl page from the Kernel Interfaces Manual (that's section 4, iykyk) 🦋 this is the resource-limits subsystem and it's genuinely iconic.

✨ NAME ✨

rctl — resource limits 🎀

---

🌸 SYNOPSIS 🌸

so if you wanna compile this driver into the kernel, you drop these two lines into your kernel configuration file, no cap:

options RACCT
options RCTL

like that's literally it, slay.

💅 DESCRIPTION 💅

The rctl subsystem hands you a flexible resource limits mechanism, okay? And the way it works is it's all controlled by a set of rules — and those rules can be added or removed at runtime using the rctl(8) management utility. main character energy fr fr 🔥

---

🎀 LOADER TUNABLES 🎀

so these tunables can be set at the loader(8) prompt, or in loader.conf(5). periodt.

• kern.racct.enable: 1 — turns rctl on ✨ it defaults to 1, unless options RACCT_DEFAULT_TO_DISABLED is set in the kernel configuration file. so basically if you set that option, the default flips and it's off unless you say otherwise. noted bestie 🙈
