Hi all. I'm totally new to beaglebone and to arch, so hope this question isn't too naive.
I'm wondering why the instructions at http://archlinuxarm.org/platforms/armv7/ti/beaglebone-black say to download and extract a new copy of the root filesystem which of course loses any new user accounts, files and other changes that may have been made to the system already installed on the SD card, rather than just copying the already-working system from the SD card to the eMMC.
I followed the instructions as far as zeroing, partitioning, and creating the new file system on the eMMC, and mounting it to /home/alarm/mnt on the running SD card system, then copied the entire running file system to the eMMC by
$this->bbcode_second_pass_code('', 'cp -ax / /mnt')
Then installed u-boot per instruction 6 to /dev/mmcblk1 and followed remaining instructions 3 and 4 to remove the SD card and reboot from the eMMC. New system seems to be working correctly. Am I missing something?
