Hi, after I saw raymii's post (https://www.olimex.com/forum/index.php?topic=3847.0) I tried the system and started tinkering with it.
After a while I creating some scripts to almost automatically create a filesystem and build a fresh kernel (with iptables support). If you edit some lines, you can add any reasonable package to your small arm debian image.. You can even modify this script to build kernel or create images for other boards.

Enjoy,
