# On a brand new Vagrant installation, we run rhnreg_ks and copy the
# systemid file to the host computer.
#
# If you later run `vagrant destroy; vagrant up`, the systemid file
# will be present on the host and copied into the Vagrant.
#
# This should help reduce the consumption of Red Hat Enterprise Linux
# Developer Suite licenses.
