Como construir uma versão customizada do FreeBSD sem privilégios de root?

Question

Eu estou tentando construir uma imagem de disco personalizada do FreeBSD a partir do código que eu poderia carregar com o bhyve.

Aqui está o script que eu uso:

export MAKEOBJDIRPREFIX="$HOME/obj"
export CHROOTDIR="$HOME/var"
ncpu="$(sysctl hw.ncpu | awk '{print $2}')"

set -e   

cd 
mkdir -p obj
mkdir -p var

svn co http://svn.freebsd.org/base/head ./src
cd src
make -j$ncpu -DNO_CLEAN buildworld buildkernel

cd release
make release -DNODOC -DNOSRC -DNOPORTS
make install DESTDIR=../../var

Meu problema é que make release falha.

O que está errado?

Aqui estão algumas partes da mensagem de erro make release :

É possível transmitir a variável NO_ROOT environmental para make : consulte Makefile.inc1 para mais detalhes.
