In a nutshell, persistent BackTrack 4 (BT4) will work if using a casper-rw named partition or a casper-rw named loop file.
However, I am not able to make the loop file option work. Any one can help?
steps that I followed to create the persistent loop file:

*EDIT*: PS, I'm experienced Debian user, and not too sure how the versioning works in Ubuntu. I mean, since BT4 is based on a old version of Ubuntu, how current is casper? Is there any online man page for the version of specific casper that BT4 uese?
