Any other messages in /var/log/messages from SELinux (not just avc)?
e.g. SELinux: security_context_to_sid(xxx) failed ...
It may be necessary to add allow rules to enable the fscontext= mount to
succeed, although I would have expected that to generate an avc denial
if that were the issue (unless suppressed by a dontaudit, but that seems
wrong). You would need to allow <processdomain>
<originalfstype>:filesystem relabelfrom; allow <processdomain>
<newfstype>:filesystem relabelto; Dan?
