Firstly, I'm a complete newbie at this so I'm probably missing something blindly obvious only a muppet wouldn't know this - but I would really appreciate being nudged in the correct direction on this one.
Basically, I've created a minimal install of Debian onto a USB key and duly followed the instructions here ->
http://wiki.debian.org/DebianLive/Howto/Custom_Install . Now that works fine and I'm pretty happy with the results and negiotated the various problems ok. But with my minimal install I want install say fluxbox and some other odds and ends. I do this using 'sudo aptitude update' and 'sudo aptitude install fluxbox wdm xorg' and this works great. The problem is that when I turn the machine off these features / libraries / binaries are no longer on the machine although I'm explictly setting the 'persistent' flag in the Grub boot list thingie.
Do I have to download these libraries separately and place them onto the USB image (and if so, how and where) or I am missing something about the Grub Boot loader, how the 'persistent' flag is used, or something else?
Thank you in advance
