Hi folks,
I have a chroot environment configured and have a user within the chroot named "jon". I'm trying to use 'passwd' from within the chroot to change his passwd in the chroot. All of the required libraries are included in the chroot's lib directories. However, when issued from within the chroot, here is the truss output:

If anyone has any idea why this could be occuring, please feel free to drop an email to either myself or the list. It would be most appreciated. It seems that passwd believes I'm not supplying any arguments.
Thanks,
Chris
