@lnussel Although People have it in their custom scripts. And this is not only
for some cross distro tools, even current SLES/Leap vs. openSUSE Tumbleweed
users will be affected. Sure, solution is simple: 
f="/boot/config-$(uname -r)"; [ -f "$f" ] || f="/usr/lib/modules/$(uname
-r)/config

But users will think: why to break compatibility for no reason (again)?

For cross distro tools you cannot rely on /proc/config.gz, because not all
distros have CONFIG_IKCONFIG_PROC enabled.
