i have set that for a very long time and it does *nothing* and even if - 
is it really that hard to behave like every other application on this 
planet and not doing such harmful things by default of if /etc is 
read-only as it should be for every network service just skip all that 
stuff and work proper?

especially when i now complain at least for *5 years* about it?
