What are you trying to do?

I have a nicer one, map build complete to "/bin/true" and i am ready in
no time. Also saves a ton of disk space.

Maybe you are looking for SSTATE_SKIP_CREATION ?

Hi Henning, it looks interesting buy it does not sound correct for my needs.

I will give it a try but I know that sscache is very useful for me but not
rootfs because it changes every time I rebuild the project.

Thanks, R-

Ok so you want to use sstate but exclude the rootfs. The variable can
be set on a per recipe basis. So you can likely bbappend to the recipe
where you want to disable sstate in your layer or in your personal
setup.
