Monitoring the system

In order to reproduce the shown output, one should:

• Fetch upstream code from the core-image-minimal recipes

$ git clone git://git.yoctoproject.org/poky
$ cd poky/
$ source oe-init-build-env
$ echo -e 'DL_DIR = "/home/user/poky/downloads"' > conf/auto.conf
$ bitbake core-image-minimal -c fetchall

• Start vmstat in another terminal (2 sec interval)

$ vmstat 2 > vmstat-output.raw

• In the initial terminal, launch bitbake, making sure no network activity will be done

echo -e 'BB_NO_NETWORK = "1"' >> conf/auto.conf

$ bitbake core-image-minimal

• Once bitbake finishes, Ctrl+D the vmstat command
