#
# Custom functions follow. Note these overwrite the
# functions in the nanobsd.sh script, so if you want to
# build your own kernel, you need to comment out the
# build_kernel and install_kernel functions contained in
# this configuration file.
#
# Functions overwritten (and their new purposes) are:
# build_world - Dummy function that does nothing
# build_kernel - Dummy function that does nothing
# install_world - Extracts world from installation tarball(s)
# install_kernel - Extracts kernel(s) from installation tarball(s)
# install_etc - Creates an empty /etc/make.conf
