# to replace the one currently installed

# Show the upstream part

# Show the pb specific part
tar tvfz /home/bruno/svn-git/pb/pbdelivery/project-builder-develXXX.pbconf.tar.gz

# Now make the packages
pb -p pb build2pkg

# Look at the latest packages created
ls -altrg /home/bruno/svn-git/pb/pbbuild/RPMS/noarch

# Install the generated packages
sudo urpmi /home/bruno/svn-git/pb/pbbuild/RPMS/noarch/*.rpm

# Docker part
# Mount the external HDD if needed

#$ sudo systemctl restart docker_registry
# Now show how easy it's to build for another distro in a Docker VE
# Create Docker container
$ docker images

# If docker issue with net, restart docker

# Building with rpmbootstrap for a distro
# We already imported the upstream container images to save time
# Start with the local distro to simplify
