I am surprised that I can't insert losetup.sh into the boot process early enough to work, but that currently appears to be the case. > In earlier post you were wondering why 'df' and 'mount' does not list some > mounted file system.

So again, thanks for the comments Jari, and also for your work in making loop-aes available. Although this is my first foray into running from an encrypted root partition, I have been using loop-aes for a very long time now, something that will no doubt continue into the future.
