I'm assuming that passwd must have successfully executed or it woudln't
have printed passwd: done. If you think ktrace wil help I'll put it in the
kernel but I will need to be pointed towards instructions on how to use it
once its in there...man -k ktrace perhaps...

This is much as above but I will try this also if you think it will
help...I might just check the source code and see if passwd does anything
after printing done.

Thanks,
