Konsole hang on remastered Knoppix /dev/pty permissions prob

Hi,

I have been working on remastering a Knoppix CD to connect to a VTUN based VPN and run some custom scripts, along with some package updates, desktop settings changes, etc. I have the CD pretty much working as I need it to, except that when you try to start a shell in konsole, it hangs and never returns. I can su to the knoppix user without any errors. The KDE message is 'kdecore (KProcess): WARNING: Can't open a pseudo teletype' and looking at the strace it seems that permissions are set on all of the device files incorrectly. How can I prevent the device files from getting all buggered like this when creating a remaster?
