I've just found a really simple way to move your Raspberry Pi operating system from the SD card to an external USB drive which is worthy of sharing.
It is done via a shell script by Adafruit which is cloned from Github to your Pi, which automatically;
- creates and formats the partition on your USB HDD
- copies across your operating system (root) from your SD card to the drive
- amends your cmdline.txt & fstab.
It does all that from one command, and having used it twice now, it's very painless!
See https://github.com/adafruit/Adafruit-Pi-ExternalRoot-Helper
There is also a in-depth guide to accompany the script if you need it, but the git readme in most cases will be all you need.

Nice find! Thanks for sharing.
Re: Running a Pi from an External USB HDD
Hello Im trying to run emoncms in the raspberri pi 2 and storing all the data into an usb HD drive, do you know this is possible by using this script?
Re: Running a Pi from an External USB HDD
The script is now included as standard within v9, so if you follow the emoncms installation guide it will guide you through it.

Re: Running a Pi from an External USB HDD
is there any point in moving everything from a wear levelling SD card to an early SSD? I'm guessing it's the same type of flash memory with the same number of write cycles?
