In the meantime I also got such a small device. For small background applications like a IPv6 tunnel router I am currently testing the headless mode.
Currently I used the way to download 2015-02-16-raspbian-wheezy.zip, unzip it and then write it to the MMC using "dd" which works successfully so far, i.e. after inserting the prepared card to the Raspberry Pi, it immediately gets its IPv4 address from my DHCP server (it's also a isc-dhcpd on a x86 Debian box) and I am able to login via SSH to continue work as expected.
On any x86/x64 PC/notebooks, I normally use the mini.iso Debian installation way where I can use partitioning for my requirements as well as setting up all important basic parameters like IP address, hostname, domain name, base package selection (my servers for example never use a GUI/X11 server) and so on. Since the Raspberry Pi has no possibilities to boot from a separate medium like the CD/DVD drive on any x86/x64 PC/notebook system, a nice way would be something like a cross installation which means that the setup routine itself runs on my Intel x86 machine but the packages are downloaded for ARM, i.e. I fully can prepare a MMC card for the first boot on my PC/notebook. => At the end, where the classic mini.iso installer says "Installation finished [Reboot system]" the cross installer should tell "Installation finished. MMC can be removed and inserted into the Raspberry Pi now" at the end.
Question: Is there a project for such an installation process?
Thanks in advance for any replies. :-)
