It's an EXT2 image file.  i.e. this file contains a perfect bitwise copy of 
what belongs on your device to get your rootfs.  Just like a hard 
disk/floppy/CD image.  You can dd if=rootfs.ext2 of=yourtargetdevicenode to 
transfer it.  Of course that will delete any pre-existing files from the 
target device so watch out.  What to put in place of yourtargetdevicenode 
depends on how you're accessing your target's storage device.
