💖 NAME 💖

login.users — the login file syntax for Firejail, bestie. it's giving "who gets what flags when they log in" ✨

🦋 DESCRIPTION 🦋

okay so picture this: the file /etc/firejail/login.users is where you write down extra arguments that get passed to the firejail executable whenever a user logs into a Firejail restricted shell. like, custom treatment per person. iconic behavior honestly 👑

every entry in this file is a user name followed by the arguments you want handed to firejail. the format is literally this:

user_name: arguments

example time, because examples ate 💅:

netblue: --net=none --protocol=unix

and here's the slay part — wildcard patterns are accepted in the user name field, no cap:

user*: --private

so one line can cover a whole lil squad of usernames. obsessed 🌸

🔒 RESTRICTED SHELL 🔒

to configure a restricted shell, you replace /bin/bash with /usr/bin/firejail in the /etc/passwd file, for each user that needs to be restricted. yes, editing /etc/passwd by hand. main character energy but make it careful 😭

alternatively (and lowkey more chill), you can specify /usr/bin/firejail using the adduser or usermod commands:

adduser --shell /usr/bin/firejail username
usermod --shell /usr/bin/firejail username

pick your fighter, both work 🫶
