Hi Andreas, I did pretty much what you plan to do. You need to have the "/boot" partition on the SD-card and the "/" partition on your SSD. I make my comments in you list below: Monday, November 21, 2016, 12:25:54 PM, you wrote: amrd> 1. dd CentOS-Userland-7-armv7hl-Minimal-1511-CubieTruck.img.xz to amrd> SD-Card correct. use another PC and connect the SD-card and you SSD. Use GParted to move your root and swap partition to the SSD. Keep the /boot partition on the SD-card. You may want to resize the /root partition to some 16-32GByte. amrd> 2. delete all Partions on SD-Card dont't! keep all partition on the SD-card. Modify /boot/extlinux/extlinux.conf and change the corresponding items. Use uuid-addresses to direct to the correct root partition on the ssd. Boot the system and check if it correctly starts from the SSD and not from the SD-disk. It it runs correctly, remove the /root and swap partition from the SD-disk. Use GParted to resize the /boot partition to use the whole SD-disk. You will need the SD-card anyway to boot the system, but there is not much R/W access to that partition except at boot time, so the speed increase is significant. I had to go through this process, because the /boot partition is too small to go through a successful kernel update. "yum update" wanted to update the kernel, it ran out of /boot-space and corrupted my system. If you need more details, I can supply more information later today. I don't have access to the system right now. best regards --- Michael Schumacher
