>Description:
I didn't have a chance to look at code, but don't want to forget this.
I emailed about it in March.

I am doing:

 find . | grep -v /.svn | cut -d / -f 2- | cpio -vvvpdm ../book

Basically, it looks for new TeX documents and copies over to a different 
directory for doing some builds. The first time (to empty ../book/ 
directory) it works fine.

I edit a file but it are not copied second time I do the same cpio. (Even 
for more than one file modified.)

The -v shows:
../book/ToC.tex

But it is not updated.

$ ls -l ToC.tex  ../book/ToC.tex 
-rw-r--r--  1 reed  staff  5545 Feb 24 14:07 ../book/ToC.tex
-rw-r--r--  1 reed  staff  5557 Mar 23 11:57 ToC.tex

It works correctly as I expect on DragonFly and also
on Linux with cpio (GNU cpio) 2.6.

I also tried using complete destination path with cpio instead of .. but 
same problem. Verbose showed the single file updated -- but it wasn't.

I also tried --insecure but I never had any warning before and that didn't 
help.

I have been using cpio --pass-through for years.

Here is example on NetBSD:

glacier:/home/reed/book/dru-FreeBSD-Basics$ cd ~/tmp
glacier:/home/reed/tmp$ date > J
glacier:/home/reed/tmp$ mkdir ~/tmp2
glacier:/home/reed/tmp$ find . -name J | cpio -vvvpdm ../tmp2
../tmp2/./J
../tmp2/./ILS/Open-ILS/src/J
../tmp2/./ILS/J
../tmp2/./ikiwiki-testbed.moved/J
glacier:/home/reed/tmp$ ls -l ../tmp2/./J J
-rw-r-----  1 reed  users  29 Mar 23 12:22 ../tmp2/./J
-rw-r-----  1 reed  users  29 Mar 23 12:22 J
glacier:/home/reed/tmp$ date >> J
glacier:/home/reed/tmp$ ls -l ../tmp2/./J J 
-rw-r-----  1 reed  users  29 Mar 23 12:22 ../tmp2/./J
-rw-r-----  1 reed  users  58 Mar 23 12:22 J
glacier:/home/reed/tmp$ find . -name J | cpio -vvvpdm ../tmp2 
../tmp2/./J
glacier:/home/reed/tmp$ ls -l ../tmp2/./J J                   
-rw-r-----  1 reed  users  29 Mar 23 12:22 ../tmp2/./J
-rw-r-----  1 reed  users  58 Mar 23 12:22 J

No change.

glacier:/home/reed/tmp$ date >> J                             
glacier:/home/reed/tmp$ find . -name J | cpio -vvvpdm ../tmp2 
../tmp2/./J
glacier:/home/reed/tmp$ ls -l ../tmp2/./J J                   
-rw-r-----  1 reed  users  29 Mar 23 12:22 ../tmp2/./J
-rw-r-----  1 reed  users  87 Mar 23 12:24 J

Still no change.

This is:
