> This forces the provisioning of separate disks in a quite messy way.
> According to the doco flowfiles and content repositories should have their
> own "disks", yet, due to the behavior above, content folder setting needs to
> point to a subfolder inside of a mount point that it dedicated to act as
> content_repository.
> Sort of bizarre. Much better would be to ensure the system accepts something
> like
> # mount /dev/vg/content_repository /opt/nifi/content_repository
> # ls /opt/nifi/content_repository
> lost+found
> # nifi.sh start
