ADDUSER(8)

💖 ADDUSER(8) — bestie edition ✨

okay so this is ADDUSER(8) from the Debian GNU/Linux system manager's manual, and honestly? it's a lil niche but SO useful once you get it. buckle up 🎀

---

🦋 NAME

adduser.local, deluser.local — the hook for local actions in adduser and deluser 💅

---

🌸 SYNOPSIS

adduser.local [username] [uid] [gid] [home-directory]

deluser.local [username] [uid] [gid] [home-directory]

---

✨ DESCRIPTION

so here's the tea, bestie 🫖 — adduser.local and deluser.local are these two lil scripts that the local admin (that's you, or your sysadmin bestie) can drop into /usr/local/sbin, and then adduser and deluser will call them respectively to do all the locally relevant setup and cleanup actions. it's giving "customize your own vibe" energy 💖

the hooks get called while the adduser/deluser lock is active. which means — and this is the important part, no cap — they must NOT call back to adduser/deluser themselves. that's a deadlock waiting to happen, and not the cute kind 😭

⚠️ fr fr: lock is held → do not re-enter adduser or deluser from inside the hook. periodt.

---

🌈 RETURN VALUE

the return values from the hooks are ignored. yep. literally just ignored 🙈 whatever you return, nobody's checking. iconic behavior honestly 👑
