 This repository contains the necessary tools to build and test cfengine packages for various platforms.
 
+## Hardware requirements
+
+By experimentation I have found that building hub packages, which includes php dependency requires more than 1.6G of RAM/swap. 2.6G worked for me, less might work as well.
+
 ## Example build of Community Agent
 
 A minimal example would be to build packages for cfengine community agent.

+In this 'buildscripts/ci' directory you will find the means to build cfengine packages.
+Note that you should ensure that the various projects are all on the same version: core, enterprise, masterfiles, nova, mission-portal all should be on say 3.21.x or 3.18.x or master.
+
+Currently a full build with no dependencies cached takes around 53 minutes with deps and packaging.
+
+Two options: containerize build or "normal" machine (such as virtual machine or actual hardware).
+
+The build is designed for ubuntu-20.04 but could be adjusted in various shell scripts for other platforms. (TODO: do this!)
+
+# containerized build
+./clean.sh # cleans any leftover docker bits
+./run.sh # builds a docker image, sets it up, runs it in the background, copies local cache into container, runs the build and saves the results
+./shell.sh # runs bash in the container for debugging
+
+See /data/buildscripts/ci/build.sh for required environment variables and steps to try manually
+
+# virtual or real machine
+
+For virtual machine such as with vagrant, at $NTECH_ROOT (aka top-level directory containing all CFEngine repositories), init an ubuntu-20.04 vagrant machine so it has access to all your repositories.
+
+vagrant init ubuntu/focal64
+vagrant ssh
+
+# note however, that currently you will need to copy /vagrant to a non shared filesystem most likely as vboxsf type doesn't support required hard and soft links for packaging :(
+set -ex
+repos="\
+buildscripts \
+core \
+enterprise \
+masterfiles \
+mission-portal \

+
+mkdir -p $HOME/workspace
+pwd
+for repo in $repos; do
+  pwd
+  cp -R "$repo" $HOME/workspace
+done
+
+# always be careful of trailing slashes with rsync, check it again if you are typing!
+rsync -avz /vagrant/cache/ $HOME/.cache/
+
+
+And then do the following as you would on a real machine:
+
+cd $HOME/workspace
+./buildscripts/ci/setup.sh # install needed dependencies/packages/etc
+./buildscripts/ci/setup-projects.sh # items which must be done AFTER the container is created with setup.sh, in non-container case must be executed second
+./buildscripts/ci/build.sh # run the build, should generate a package
+
+don't use ./clean.sh ./run.sh or ./shell.sh those are specifically for containerized/docker build
+
+If you are running selenium tests in mission-portal, you might need to do a `make -C mission-portal clean` before creating packages as the selenium tests copy some things from the distribution into the repository directory that cause problems with packaging, such as the api directory from nova.
+
+# manual debugging on-host
+
+cat buildscripts/ci/build.sh
+# now export the environment variables there (and adjust as needed)
+export BUILD_TYPE=DEBUG
+export ESCAPETEST=yes
+export TEST_MACHINE=chroot
+
+then take each step one-at-a-time or re-run as needed
+
+./buildscripts/build-scripts/install-dependencies
+
+Note that you can provide an argument to install-dependencies to just build ONE dependency, such as
+
+./buildscripts/build-scripts/install-dependencies lmdb
+
+If you change the version of a dependency the cache for that should be skipped and the dep rebuilt from scratch.
