[Samba] sernet documentation

[Robert Moskowitz]

One of the Centos 7 arm developers built the sernet 4.2 for me to start 
testing.

http://repo.shivaserv.fr/centos/7/shivaserv-sernet.repo

and

http://repo.shivaserv.fr/centos/7/sernet/armv7hl/

Since these were built on qemu, not requiring specific armv7 hardware, 
Perhaps at some point they can be adopted by Sernet.  But for now, how 
to test....

I don't see any specific Sernet documentation.  Like what is here and 
how to set it up, perhaps different, from generic Samba 4.

I searched the sernet web site and this list and came up empty, but my 
search foo is weak.

thanks
