The goal of this was to swap /data and /sdcard with usb storage so that i could install unlimited apps and games. Swapping them does come at the price of speed as the usb interface is not as fast as the internal storage. Bascially you could do the same thing with stickmount and link2SD, but then you have to deal with stickmount and link2SD....

Thanks to rbox for recovery and jocala for UUID idea.
Warning: This will make your fireTV run slower. This works best on a clean install, but should work either way. You may see a pixelated screen on first boot and it will take a few minutes while files are copied to USB, just be patient.
There are now 3 versions of the scirpt pick your poison:
1. the original MountDataToUSB which mounts your USB drive to /data (except /data/misc). This is the total solution for external usb drive hard drives plugged into powered hub only. External Hard Drives only, DO NOT USE WITH USB THUMB DRIVE.
2.. MountPartialDataToUSB Same as #1 except it leaves /data/misc /data/system and /data/data mounted to internal storage. The downside is when you install new apps some stuff does get installed to /data/data which takes up internal storage space. Tested with USB 2.0 thumb drive and UI seems as fast as stock.
3. MountMediaToUSB which mounts your USB drive to ONLY /data/media (and the fuse mount point /sdcard) expanding where game OBB files are stored (similiar to sticking an SD Card in your phone). This should be about as fast as stock fireTV except when accessing data off /data/media but this doesn't expand /data/app
I've made this into a CWM flashable now to simplify things. You need to have the following pre-requisites:
Instructions:
1. Plug in ext4 formatted USB Drive
2. adb reboot recovery
3. Factory Reset (optional but recommended, some users have reported errors if they don't. Also first boot will take longer while it copies all files from data). If you factory reset make sure you are blocking updates.
4. Flash zip in CWM. MAKE SURE THAT ONLY YOUR DRIVE YOU WANT AS DATA IS PLUGGED IN WHEN YOU FLASH v3.0 and newer zips THAT IS WHEN THE UUID IS READ and stored.
4. Reboot (first boot may take a few mins while files are copied, pixelated screen may display for couple minutes be patient). May be very laggy while it is downloading everything from the cloud to your usb drive, but should speed up a bit after it's done.
5. a. If using full data mount - Check System about for available disk space .
b. if using Media Mount only - run this command from shell and view available storage on media:
Details: When the script first starts it waits up to 30 seconds for /dev/block/sda1 to come up. If it doesn't come up (or if the usb drive is not plugged in) then it boots from internal storage. It then checks for the folder "/data" on the usb drive, if it doesn't exists it copies the files from the internal storage to the USB drive. Everything under /data is mounted to usb storage with the following exceptions /data/dalvik-cache /data/misc and /data/resource-cache
IMPORTANT: The internal storage is mounted to /data_fire if you need to flash anything in CWM copy it to /data_fire/media/0/ as CWM does not see the ext4 usb storage
I've also included a revert script (REVERT_MountSDCARDtoUSB.zip) to undo the changes in case something doesn't work. Just flash with CWM.
If you have issues check/post the output of /storage/usb/moutUSB.log
Just be aware if you update the firetv image with one of rbox's pre-rooted roms you have to re-flash this zip after right after.

I've made this into a CWM flashable now to simplify things. You need to have the following pre-requisites:
1. Rooted with rbox's CWM recovery installed
2. ext4 formatted usb drive I recommend using the full drive, but it should work as long as it's the first partition
(google how to do this).
3. This script won't work with multiple drives plugged in as it mounts /dev/block/sda1 which is the first drive detectedMounts by UUID now so you can use jocala's BusyMount script to mount other drives after.
4. The ext4 forrmatted drive must be the only drive plugged in when flashing the zip because it grabs the UUID off of it while flashing.
Instructions:
1. Plug in ext4 formatted USB Drive
2. adb reboot recovery
3. Factory Reset (optional but recommended, some users have reported errors if they don't. Also first boot will take longer while it copies all files from data). If you factory reset make sure you are blocking updates.

Change log:
Update 2014/11/18 - v3.1 - Recommended Added KhoaTon's fix for drives with a LABEL set. See post 163 in this thread for details.
Update 2014/11/03 - v3.0 - All versions now mount by UUID. Synced all version numbers. Fixed bug in MountMediaToUSB. MAKE SURE THAT ONLY YOUR DRIVE YOU WANT AS DATA IS PLUGGED IN WHEN YOU FLASH v3.0 zip THAT IS WHEN THE UUID IS READ.
MountPartialDataToUSB_v1.0.zip [For usb thumb drives or Hard drives] Same as MountDataToUSB_v2.5 except it leaves /data/misc /data/system and /data/data mounted to internal storage. See notes above for specifics.
MountMediaToUSB_v1.0zip [For usb thumb drives or Hard drives] - Mounts only /data/media to the USB drive. Should should keep most of everything at normal speed, and expand /data/meda and /sdcard storage. This is where OBB files for games are usually stored.
MountDataToUSB_v2.5.zip [For external hard drives ONLY]- Same as v2 except re-named zip to MountDataToUSB.zip and re-named script and log file to "mountUSB.sh" an "mountUSB.log". Also fixed permission on /data_fire/media/0 so it's easier to push files directly to it for flashing in CWM. Fixed bug with /data/media/0/0 folder.
v2.MountSDCARDtoUSB.zip - (originally posted on page 3) mounts everything except for /data/misc to the usb storage
REVERT_MountSDCARDtoUSB. - Flash this to revert back to normal.
