debian based dtstro that's designed for flash USB sticks > 64Mb

[Nick Lidakis <nlidakis@verizon.net>]

Have been searching  on Google and on linux.org for a debain based linux 
distribution that is bootable from usb flash memory but will also allow 
you to apt-get pacgakes and install on the USB media as  needed. I will  
be using with a 256MB flash key.

Most of the distros I have found on google focus on small 50mb images or 
distros that can only install secondary software  (e.g.  Feather Linux) 
once installed on a hard drive.

Any ideas or links would be appreciated.
