335681ca8e su: FEATURE_SU_BLANK_PW_NEEDS_SECURE_TTY 
When this feature is enabled, blank passwords are not accepted by su
unless the user is on a secure TTY defined in /etc/securetty. This
resembles the default PAM configuration of some Linux distros which
specify the nullok_secure option for pam_unix.so.

Based on patch by Kaarle Ritvanen <kaarle.ritvanen@datakunkku.fi>

67918b32ab fallocate: new applet 
NAME
       fallocate - preallocate or deallocate space to a file
SYNOPSIS
       fallocate [-c|-p|-z] [-o offset] -l length [-n] filename
       fallocate -d [-o offset] [-l length] filename
DESCRIPTION
       fallocate  is  used  to manipulate the allocated disk space for a file,
       either to deallocate or preallocate it.  For filesystems which  support
       the  fallocate system call, preallocation is done quickly by allocating
       blocks and marking them as uninitialized, requiring no IO to  the  data
       blocks.   This  is  much faster than creating a file by filling it with
       zeroes.
