I updated the installation guide for Juno release packages as follows: 1) Converted 'systemctl' commands to single lines. 2) Converted more sections to use 'systemctl' commands. 3) Added note about lengthy installation time for 'openstack-selinux' package. 4) Explicitly configured UUID tokens and SQL driver in keystone. RDO needs to update or remove the 'dist' configuration files for services. 5) Explicitly configured local file system store options in [glance_store] section that appeared two days before official release. Although the Ubuntu and RDO packages appear to work by default, late changes to configuration files tend to cause problems at some point. 6) Explicitly configured authentication strategy to keystone in nova on controller and compute nodes. I think we should avoid relying on defaults for this option and reconsider for Kilo, particularly with RDO packages. 7) Explicitly installed 'sysfsutils' package on nova compute nodes because nova looks for it during cinder volume operations. 8) Removed explicit installation of 'ipset' package on neutron network and compute nodes because the Ubuntu and RDO packages install it as a dependency. Not sure about SUSE, so I left the explicit installation. 9) Changed cinder example devices from /dev/sdb to /dev/sdb1 because LVM on CentOS didn't like the former. Note: The configuration changes mostly apply to RDO packages on CentOS, but given the time constraints, I fixed some other issues. Also, this patch ignores the sahara chapter.
