OK.  Makes sense.  Since I have full steps.txt for each of my servers, I 
don't have THIS confusion problem.

I was field testing uboot for Hans back at the time and was locally 
building my own uboot from his source.  I have since long deleted all of 
that environment and Hans has moved on to other work.

But he DID get sata boot working with only uboot (no partitions allowed) 
and was working on a bug for usb boot.  He did not get things like the 
wifi working and a few other odds and ends.  Never checked in to see if 
later uboot maintainer finished up the work.

I run all my servers on Cubies (well not my Samba which is ClearOS, and 
they don't have an arm image last I checked)  That picture on the web 
site is my webserver, internal and external DNS servers, and backup 
(that I may move to my neighbor's, as I have ethernet running to his 
house).  The 4th is a spare.

My mailserver is a Cubietruck.  Antispam pretty much kills one 
processor, and that is why I am interested in the C5.  I have limited my 
attachment size to 20MB.  My wife complains, and I really need more 
cores so I can handle bigger attachments without slowing everything 
down.  Well I/O would still be an issue and that is why the sata 
performance concern.

Hopefully now that you have C5 working with a new kernel, you will push 
out a new image so that it is 'easy' to use.  Also an update to Centos 
of uboot-images with those in F29.

You can get a 100GB from ebay really cheap.  Make sure it is 500ma, so 
it powers easily from the board that is powered by a 3A USB source.  I 
use the ANKAR 40W to power 5 Cubies.  600ma seem to work ok.  Not 1A drives.

I don't know anyway to move the uboot to NAND.  If I were shown how, I 
would risk a C2.  I mean it is not bad to tie up the uSD slot with 
uboot.  I am not going to use it for anything else, and everything boots 
fast enough with all the partitions on sata.

And with the Fedora-arm testing I do, I have a pile of uSD cards.  I am 
using F29 as a source of openssl 1.1.1 for my EDDSA pki testing 
(https://github.com/rgmhtt/draft-moskowitz-ed25519-pki).

I need to finish this up before I work on my mailserver.

And 1.1.1 is a requirement for TLS 1.3, so I hope when it goes live, you 
port it to C7!
