After a restart metadata-providers.xml does have this:
<MetadataProvider id="SiteSP2"
xsi:type="FilesystemMetadataProvider"
metadataFile="/opt/shibboleth-idp/metadata/65E7DC02E919BF370002D6060C0F0006DF55E488-sp-metadata.xml">
</MetadataProvider>
</MetadataProvider>
But when testing testshib, I'm still getting:
