I am planning to install Arch Linux on my new Raspberry Pi.
But I have a requirement. Raspberry Pi always boots from SD card. But I want it to boot from USB. This is because I already have a USB disk bootable with Arm Linux installed. I had took a lot of pain to install a lot of stuff and configure the OS earlier on my hard disk (it was attached to a TonidoPlug which got burned 2 days back). I am trying for options to make sure I don't need to re install all stuff and configure everything again. So I wish I could boot from the existing boot partition on my USB disk.
I found this link which says how I can boot to Raspbain OS from USB (a hack on the boot config) -> https://www.raspberrypi.org/forums/view ... 66&t=12015
Is it possible to configure ArchLinux such that I can boot from USB like above?
