Oops..
please ignore my previous mail.
Instead, this is what the issue is (seems this issue has put me in mental
sleep; I am making stupid, idiotic mistakes) :|

Anyways, here it is .. (again, please ignore my previous mail completely)
::::





If we do the following ::

a)
In OpenFirmware CLI, do

                      enable-security <my XO-1 serial number>


b)
And there is NOT any "/security/develop.sig" file in my pendrive while
booting.



c)
There is NOT any "/security/develop.sig" file on the XO-1,




it is observed that ::


i)
mesh-icons are observed in neighborhood-view, both during reboot and
resume-from-suspend.

ii)

"/var/log/messages" show the loading of "msh0". However, there are no
exceptions/crash-traces therein.

iii)

Also, I see the presence of a folder "/sys/class/net/msh0".



PLEASE NOTE THAT IF ANY OF a), b) OR c) CONDITIONS ARE NOT MET, THE  MESH -
ICONS ARE NOT OBSERVED (AS IS VERY MUCH EXPECTED).




Is my observation in line with anyone's observation on olpc/sugar?
(Note that the issue was reported by UY deployment; and it could be
reproduced at our end as well).



Kindly reply with comments.



Thanks and Regards,
Ajay
