[STUMP] Authentication agent under stumpwm - lxpolkit?

[Johnny]

Hi,

What is the preferred way to run an authentication agent under
stumpwm? I have stumpwm installed on a Fedora LXDE install, so have
lxpolkit available but this is not automatically started by the stumpwm
session. To e.g. run a virtual machine, an authentication agent must
run, so I just 

: /usr/libexec/lxpolkit &

Is there a better way to run an authentication agent under stumpwm? How
do other users do?

Cheers,

Johnny
