Hmm...  Very interesting, but strange... but interesting... question.  Makes
me wonder why you are so set on building SLES for an embedded board?
But that's not for me to second-guess.  :-)

As pointed out the family of OpenEmbedded-based systems provide their own
set of build recipes ("layers") and several different reference
distributions (with appropriate patches and so on).  

For source availability, I liked the analogy with building RHEL vs Fedora,
although on that side CentOS source distribution is available as a very
close duplicate of RHEL.  If you wanted to do something similar to meta-
debian what basis were you thinking of using in order to create your own
SLES if not OpenSUSE?  (Actually answering that would veer the thread off-
topic for the list I imagine, I'm just curious).

Related to the topic, the only similar ideas that I have seen floated in the
past involved using Debian source code with OE/Yocto build system.  I
suppose the idea for that would be that you have a strong handling of
security updates a compatible basic distro and of course a very large amount
of packages.  

I still think it's a fairly strange approach since building Debian using
Debian tooling might suffice in that case (e.g. [2]).  You might get a bit
of a larger ecosystem of available BSPs in OpenEmbedded/Yocto environment
and a few additional embedded-targeted components (but a lot are built
with fairly standard setups like cmake anyway).  It wasn't clear if you need
a lot of different hardwares or just any board like minnowboard.

I was going to link the meta-debian layer, but it seems the Linutronix
slides cover this and more alternatives, so (for those interested in the
Debian/Yocto idea I mean) just start with that slide deck (and search
GitHub).
