# I use this tar command to create the image of an already running and configured machine
# tar -cf /tmp/IMAGE.tar --exclude /tmp/\* --exclude /run/\* --exclude /proc/\* --exclude /sys/\* --exclude /dev/\* /
# add --xattrs --selinux --acls if needed (for CentOS 7)
# Then copy this image to /srv/fai/config/basefiles/IMAGE.tar and make sure your client belongs to the class IMAGE

# things that may be adjusted:
#
# MAC address ?? (not needed for Ubuntu, it uses iftab(5)
# /etc/hosts may contain the IP and name of the original host
# /etc/hostname (for Ubuntu just remove it)
# /var/lib/NetworkManager/dhclient-eth0.conf?
