I have serverhostname.mydomain.net:1 there, perhaps due to creating 
arrays
not on install time, but long after the OS has been already installed 
and set
up properly with all the networking, domains and hostnames.

In any case, you can change that name to your liking, and then replace
"UUID=..." with "name=..." in mdadm.conf, if that helps anything with 
your
intended configuration

not really and that is the point: i talk about a system where 
boot+system itelf is on top of the array

there is no real solution and nobody has *real* expierience here - 
trial&error can i do at my own given that half of the existung RAID10 
will ly on a desk and whatever happens a resync and start from sract is 
possible at any point in time

just for fun: that "name shit" was even different on two machines cloned 
by take out 2 of the 4 disks and rebuild both machines

thanks to UUID it didn't matter
