NAME         top

       firejail.users - Firejail user access database

DESCRIPTION         top

       /etc/firejail/firejail.users lists the users allowed to run
       firejail SUID executable.  root user is allowed by default, user
       nobody is never allowed.

       If the user is not allowed to start the sandbox, Firejail will
       attempt to run the program without sandboxing it.

       If the file is not present in the system, all users are allowed to
       use the sandbox.

       Example:

            $ cat /etc/firejail/firejail.users
            dustin
            lucas
            mike
            eleven

       Use a text editor to add or remove users from the list. You can
       also use firecfg --add-users command. Example:

            $ sudo firecfg --add-users dustin lucas mike eleven

       By default, running firecfg creates the file and adds the current
       user to the list. Example:

            $ sudo firecfg

       See man 1 firecfg for details.

ALTERNATIVE SOLUTION         top

       An alternative way of restricting user access to firejail
       executable is to create a special firejail user group and allow
       only users in this group to run the sandbox:

            # addgroup --system firejail
            # chown root:firejail /usr/bin/firejail
            # chmod 4750 /usr/bin/firejail
