yes

these hosts also need maintenance so I actually prefer the first.

aint there a makefile with a proper target? Also how to build these cross

yes, please. best a complete runnable script, aka a _working_ 5-10 liner, not 
the fancy one with variations, rebuilds and running debbindiff. Just the above 
"4 lines in working" - (those 4 lines dont work cause the variables are not 
defined...)
