It is pretty much stock except for these few changes:
- rooted
- busybox
- kernel repacked for ext4 vs ext3
- kernel repacked to remove new htc /lib partition for use on all hboots
- remove htc linkify crap (app associations as a result of apple lawsuit)
- removed a lot of the htc log/testing utilities that are present (theyre neat to play with sorta, but the avg user would get annoyed by their notificaitons always being on)
- moved some stuff to /data because older hboots dont support /lib and /lib needs to be back in /system/ (which didnt have the room for it all)
