Thanks for the answer,
although i am not using Portage, only equo. My question maybe was not clear enough. I was asking this in general not for myself personally ... yust more like a suggestion for those "bloody Linux Newbies" ... which are mostly afraid to make such an update manually (i did it once with success although it took me some time !) without using equo.
So my suggestion in my question (sorry about that !):
Would it be possible to bring in a special case like this = critical emergency update ... this update via an upgrade over the equo repos more quickly ?
I know that normally it goes first in the limbo repo's and a week later arrives at the Sabayonlinux.org Standard Repositories !
