Hello there,
I have managed to run R3 using UNetbootIn in an 8 GiB flash drive. Added the remaining 1.2 GB for persistence so I can keep my files etc.
The problem is, I do not want other people to be able to mess with the USB Stick if they find it [Boot it etc.].
I tried a simple
to change the root password but it doesn't seem to prompt on boot.

Is there any way I can request login during boot or even encrypt the drive and request the decryption password on boot?

Thanks a lot.

P.S.: I am installing BT5 using "Install Backtrack" on another 8 GiB flash drive right now hoping it will work but still needs about 20' to go.
