Here we use it at distro and use previous distro in override as well
reducing this diverging problem.

We do it as making a new distro for each product that include the
"base" and changes what is required providing a new distro that has
all base distro as base for settings, versions and like.

In your case it might be:

 mamona.conf
 mamona-vanilla.conf
 mamona-foo.conf

This could avoid the multiple TMPDIR issues. We added here a
DISTRO_MACHINE_ARCH so in case the configuration is specific to a
machine and distro we use it, instead of MACHINE_ARCH allowing for
speedup in compilation and sharing the TMPDIR for those.
