What release am I running?
Identifying build number
If you are sure that you are running an official release produced by OLPC (as opposed to a deployment), you can follow the techniques below to identify the build number, and then refer to the table to see which release it corresponds to.
If you are not running an offical OLPC release (e.g. you are running a development release, pre-release, or deployment build), or if you are unsure, skip to #Identifying release information to determine the version information in more detail.

Identifying release information
If you are running a software version that is not an official release (e.g. a pre-release), or are unsure, the following instructions will help you identify the version information.
From the terminal
The following commands from the Terminal activity should reveal information about the release you are running:
cat /etc/olpc-release cat /etc/issue olpc-netstatus -i
From the console
The console displays the build number, until it scrolls off the top of the screen.
- Press ctrl+alt+F2 (the F2 key is the same as the Group key
. The Ctrl key has a solid diamond on it (♦); the Alt key has an open diamond on it (♢). See Keyboard Shortcuts for more details.) - Read the build number from the first line of text that appears in the console window
