bug#12421: Issue of the cp on Ubuntu 10.10

[owen . zhao]

Dear Sir,

A strange issue happens when I use the cp tool on two directory.

1  I have an empty directiry
address@hidden:~/work/ALi_SDK/DailyBuild/linux_20120911$ ls 
images/fs.install/ -a
.  ..

2  Then I cp an directory in this directory with -rf
address@hidden:~/work/ALi_SDK/DailyBuild/linux_20120911$ cp 
extern/fs_install/* images/fs.install/ -rf

We can find the file busybox size is 998K now.

address@hidden:~/work/ALi_SDK/DailyBuild/linux_20120911$ ls 
images/fs.install/bin/busybox -lh
-rwxr-xr-x 1 owen owen 988K 2012-09-11 21:37 images/fs.install/bin/busybox

3  In another directory, we have a same file with the same size
address@hidden:~/work/ALi_SDK/DailyBuild/linux_20120911$ ls 
extern/fs.install/bin/busybox -lh
-rwxr-xr-x 1 owen owen 988K 2012-09-11 15:02 extern/fs.install/bin/busybox

4  Copy the content of the extern/fs.install/bin/busybox to 
images/fs.install
address@hidden:~/work/ALi_SDK/DailyBuild/linux_20120911$ cp 
extern/fs.install/* images/fs.install/ -rf

5  Check the size of busybox
address@hidden:~/work/ALi_SDK/DailyBuild/linux_20120911$ ls 
images/fs.install/bin/busybox -lh
-rwxr-xr-x 1 owen owen 526K 2012-09-11 21:39 images/fs.install/bin/busybox

Anything I missed when I copy ? The size is changed dramatically.

Best Regards
Yours (Owen)
