# The user building the ISO has to be part of the 'abuild' group and because we're in Docker things are a lot easier if
# we run as root, so we need to set a root password, unlock the user, and add it to the group.  We also need to run
# abuild-keygen through sudo in order for it to pick up root's new group membership.
