In Liberty, the database connection option for services that use a SQL
database contains "mysql+pymysql://" which uses the PyMySQL library instead
of "mysql://" which use the conventional MySQL-Python library. The RDO
repository doesn't contain a package for PyMySQL. Development of the
upstream installation guide cannot continue without this package because
the workarounds either involve installing this library via pip which
potentially leads to versioning conflicts with packages or changing the
database connection option everywhere specifically for RDO.

I think packages available for standalone installation (i.e., without
a
deployment tool) should include complete upstream configuration files in
standard locations without modification. In the case of *-dist.conf files
with RDO packages, they seldom receive updates leading to deprecation
warnings and sometimes override useful upstream default values. For
example, most if not all services default to keystone for authentication
(auth_strategy), yet the RDO neutron packages revert authentication to
"noauth" in the *-dist.conf file. In another example, the RDO keystone
package only includes the keystone-paste.ini file as
/usr/share/keystone/keystone-dist-paste.ini rather than using the standard
location and name which leads to confusion, particularly for new users. The
installation guide contains quite a few extra steps and option-value pairs
that work around the existence and contents of *-dist.conf files...
additions that unnecessarily increase complexity for our audience of new
users.
