Other openstack components may be importing python's libraries to be used in middleware during unit tests. Keystone is one such package, and its swift tests fail to build on Ubuntu buildds:

It appears that swift unconditionally sets its logging to use syslog via /dev/log, even if (in this case) the log handlers will probably never be used. There is no way for users of library (keystone's swift_auth middleware, in this case) to specify alternative log methods, or to disable entirely. This is a problem for anyone attempting to run unit tests in a constrained environment.
