setsebool(8)

✨ setsebool(8) ✨

okay bestie, gather round, because setsebool(8) is literally the little command that flips SELinux booleans on and off and it's giving main character energy 💅

---

🎀 NAME 🎀

setsebool — set SELinux boolean value. that's it. that's the job. she sets booleans. iconic behavior fr fr 🦋

---

🌸 SYNOPSIS 🌸

setsebool [ -PNV ] boolean value | bool1=val1 bool2=val2 ...

---

💖 DESCRIPTION 💖

so like, setsebool sets the current state of a particular SELinux boolean — or a whole list of booleans, because why do one when you can do many — to a given value. slay.

and the value? it's flexible bestie:

• 1, true, or on → enable the boolean ✨
• 0, false, or off → disable it 💀

now here's the part you actually need to hear, no cap:

• Without the -P option, only the current boolean value is affected. the boot-time default settings are not changed. so yeah, it'll vibe for now and then forget everything after a reboot 🙈
• If the -P option is given, all pending values are written to the policy file on disk. meaning they'll be persistent across reboots. this is the one you want if you're tired of redoing your work every single time, periodt 👑
• If the -N option is given, the policy on disk is not reloaded into the kernel. noted.
• If the -V option is given, verbose error messages will be printed from the semanage libraries. so when something goes wrong you get the whole story instead of a cryptic little nothing 🫶

⭐ EXAMPLE ⭐

Enable container_use_devices boolean (will return to persistent value after reboot) — so it's cute for now but it's not staying 💅

# setsebool container_use_devices 1

Persistently enable samba_create_home_dirs and samba_enable_home_dirs booleans — two at once, using the bool=val format, and with -P so it actually sticks around 🔥

# setsebool -P samba_create_home_dirs=on samba_enable_home_dirs=on
