# Prepare ubuntu 14.04 for building RPMs with mock.
#  - older versions of mock needs the config file to reside in /etc/mock,
#    so we copy it there.
#  - add a mock system group (if not already exists)
#  - add the current user to the mock group.
#  - prepare mock environment with some needed packages.
# NOTE: This target should be run with sudo.
