The invalid prefix user is another artifact of semanage/seobject.py
trying to check something against the host's policy rather than checking
against the target policy just due to lack of adequate libsemanage
interfaces.  Calls to is_selinux_mls_enabled() and
security_check_context() need to be turned into libsemanage calls.

The could not query record value one is too generic.  Might help to get
a snapshot of the /etc/selinux/targeted tree that it built and see
what's there.  Or possibly patching libsemanage to give more useful
output, but it's a bit hard due to abstraction layers there.
