The Google TV File System is similar to most other Android Operating Systems.
Updates
Updates to the Google TV, unlike most the incremental updates that most Android phones receive, come as a complete file system meant to replace the previous. It is assumed that since Google TV devices are meant to be connected to high speed internet connections, downloading a full File System is more palatable than on a limited-bandwidth mobile device.
Updates are retrieved without user intervention from the Google Servers. You can use the device version number to check your current file system implementation (See [GoogleTV - Version Numbers] for more information). Updates are distributed as signed zip files including a recovery, system, and userdata image. The current update packages are:

How to access the File System contained within an image
The Zip File is a simple matter to extract, however the images within them tack some massaging in order to explore. While they are a typical SquashFS File System, they have some padding bytes that prevented a simple "Unsquashing."
- It would be great if we could create a way to use dd to truncate the image instead of using a hex editor. You should be able ot somehow grep for the start and then dd the proper bits into a new file that could be explored correctly.*
Some data on the process is available here: http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images
GTV Recovery Mode vs GTV(System) Mode
GTV Boot Loader
The Boot Loader is included on the File System, currently in the X directory. The Boot Loader is based off of the Y Loader (More information can be found at Z). For the Sony BlueRay player, the Boot Loader is ABC.
