deterministic-exit-code
              Always exit firejail with the first child's exit status.
              The default behavior is to use the exit status of the
              final child to exit, which can be nondeterministic.
       join-or-start sandboxname
              Join the sandbox identified by name or start a new one.
              Same as "firejail --join=sandboxname" command if sandbox
              with specified name exists, otherwise same as "name
              sandboxname".
