okay bestie, welcome to the File Formats Manual — yes, we're in proc_pid_setgroups(5) territory and it's a short one but it's mighty, so let's go 🫶

✨ NAME ✨

/proc/pid/setgroups — allow or deny setting groups

🌸 DESCRIPTION 🌸

/proc/pid/setgroups (since Linux 3.19) — yes she's a baby, a 2015-era icon, and she does exactly what the NAME says: she's the little knob that says whether setting groups is allowed or denied. 👑

And like… that's it?? That's the whole description?? Because the real tea lives somewhere else, bestie:

See user_namespaces(7).

no cap, if you want the actual lore — the why, the how, the whole user-namespace cinematic universe — you HAVE to go read user_namespaces(7). this page is not gonna spill it for you and honestly? respect. 💅
