Putting installation media on a USB key
Just use the SuSe ISO media writer (ships with Manjaro-Arch live CD.ISO) - or try others like unetbootin etc. - and put the ISO onto SD card.
Bootup and install does do work then (March 2016 situation).
The Parabola MATE live CD at Parabola_MATE_desktop_ISO has a menu driven installer.
