I'm trying an experimental sandbox setup here. I have my X server itself in a jail (needs a kernel patch and some =20 devfs rules), and in the past connected to a jail and started a X11 =20 programm there...

How do =20 you start the jail? There should be devfs mounted in the jail. Bye, Alexander. --=20 "How do I love thee?
