\frametitle{override default config files}
default templates can be overridden by setting TEMPLATECONF
to e.g. meta-mini/conf during ./oe-init-buildenv.
Then meta-mini/conf bblayers.conf.sample and local.conf.sample will
be used.
The default location is specified in
\begin{verbatim}
% cat .templateconf
# Template settings
TEMPLATECONF=${TEMPLATECONF:-meta-yocto/conf}
\end{verbatim}
