pw(8) often generates an shorter password than eight letters when I try 
random password generation option.

Fix: The functiton 'pw_password' in /usr/src/usr.sbin/pw/pw_user.c should be fixed.

                pw_getrand(rndbuf, l);
                for (i = 0; i < l; i++)
!                       pwbuf[i] = chars[rndbuf[i] % (sizeof(chars)-1)];
                pwbuf[i] = '\0';

How-To-Repeat: Place 'defaultpasswd = "random"' in /etc/pw.conf and execute 'pw useradd
-n name'.
