Whenever I chroot into my remaster, I get the following:

/bin/bash: /dev/null: Permission denied
/bin/bash: /dev/null: Permission denied
/bin/bash: /dev/null: Permission denied
/bin/bash: /dev/null: Permission denied
and so on.
I've tried doing a chmod 777 /dev/null, I've tried doing chgrp and chown root /dev/null, and I still get the same error. I searched Google for solutions, but their problems were all fixed after a chmod 777, whereas mine still persists.
I can delete /dev/null and it regenerates one and works, but then the remaster fails to work when installed onto the HD, and the regenerated /dev/null is quite odd - it's not even a device file. Any thoughts?
