I think that it should be a bug, would you please try this patch?<br>

(This is my first post to OE list, hopefully I am posting to the right mailing<br>
list.)<br>
<br>
Background: During the process of trying to configure SSH keys for root user<br>
login via dropbear, we realized the permission for /home/root directory is set<br>
too loose for group and other members [1]. As a result, dropbears fails when we<br>
try to put the key under /home/root/.ssh<br>
<br>
---------<br>
<br>
In the image, /home/root directory is set to 0755:<br>
<br>
$ stat /home/root<br>
File: /home/root<br>
Size: 4096 Blocks: 8 IO Block: 4096 directory<br>

Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root)<br>

Change: 2016-04-05 22:08:57.000000000<br>
<br>
<br>
After some debugging, we believe the permission (0755) is initialized in<br>

<br>
A few questions:<br>
1. I tried looking at the git log for the history, but wasn't able to find any<br>
background on why the permission was set this way. eg. on a desktop Linux<br>
(Ubuntu), /root is set to 0700:<br>
<br>
$ sudo stat /root<br>
File: `/root'<br>

2. If we would like to override the directory permission for /home/root in our<br>
image, what is the best way to do it? I am not an expert with bitbake, should I<br></span>
be patching the <a href="http://base-files_3.0.14.bb" rel="noreferrer" target="_blank">base-files_3.0.14.bb</a> <<a href="http://base-files_3.0.14.bb" rel="noreferrer" target="_blank">http://base-files_3.0.14.bb</a>>? using<span class=""><br>
*_append? or I should be looking at some other recipe altogether?<br>

Sorry for the long email. Thanks in advance.<br>
