[arm-allstar] Cloning of SD card with Hamvoip installed.

[Rachid Karroo]

Good day Doug
Thank you very much for all the info.

You know what I like about this list, is that no question remains
unanswered and there is always somebody somewhere willing to help in the
true spirit of Amateur radio. I thank you Doug and all for that !!

I will give it a try during the week-end and I will keep you posted via
direct msg.
