This is required to ensure that SELinux is configured properly while
building. It fixes the problem with building tar, and should be
installed in the other image types for consistency.
Resolves: rhbz#1645189
Since these images can be used to create multiple machines, they should
not have a unique machine-id attached to them. Replace /etc/machine-id
with an empty file so that it will be regenerated at boot time.
This differs from lmc's --make-ami in that creates a full disk image instead of
an fsimage. Create a raw disk image with a / and /boot partitions, and enable
sshd, chronyd, and cockpit by default.
