I suppose this is a getpass() problem ?
This is intended operation as su(1) may not always be affiliated with a
TTY. This leaves it open for a script to chat with much like what samba
does with its passwd chat mechanism.
well, all other oses (netbsd, openbsd, ubuntu at least) don't do it this
way, they all password prompt to /dev/tty instead of stdout. freebsd is
the only one which prompt to stdout.
