How does this variable interact with binpkgs? For example, if I build a package on a system that does not have CONFIG_CHECK_FATAL=0, what happens if I try to install it on a system that does not have a usable kernel config? My suspicion is that portage's environment save/restore process will overwrite any setting I attempt to make on the destination host.
