Analysis of IMEI numbers

All mobile phones are assigned a unique 15 digit IMEI code upon production. Below you can check all known information regarding manufacturer, model type, and country of approval of a handset.

Tip! The IMEI can be displayed on most mobile handsets by dialling *#06#. Otherwise check the compliance plate under the battery.

Egan said aufs.ko should be complied and put into the directory contained genimage; I will have try.

StatelessLinux for Fedora

http://fedoraproject.org/wiki/StatelessLinux

 Stateless Linux

Stateless Linux is not a deployment model. It is not any single technology. It's a new way of thinking about how a system is supposed to run and be managed.

To be stateless, a system should be able to be replaced at any time, whether it's running diskless or with local storage. Hard drive crash? Just resync your remote image to a new drive, and you're good to go. Server goes offline? Start a new virtual instance running your OS image off of your network storage.

Moreover, it's about being able to run multiple machines from identical OS metadata. Instead of managing each machine independently, the single copy of the OS metadata is managed.
