here you find images for many linux distributions, actually theyre just a minimal install...i will follow with different releases for different use, as example lamp server, desktop and more
the best reason to install these, is that i enabled iptables out of the box and uncomplicated firewall (ufw) is installed, which is not (yet) done by the stock images here on pcduino.com.
those images can be installed with dd under linux/mac or win32diskimager from windows
root password is mostly empty, except root password for arch image is root itself
for installing it to sdcard you need at least 2gb because they images were made to fit on these cards...to expand it to the realsize of your sd card you can use any partition manager gui as gparted.
enjoy and pls let me know if there is an issue, question or something like that
