I assume that dbcfs is the relevant filesystem? So you are using
mountpoint labeling, i.e. passing context= to the mount command with a
specific security context to use, and the policy doesn't know anything
about this filesystem type. So its initial label is unlabeled_t, and by
passing a context= option, you are triggering a relabelfrom check to see
if the mount program is authorized to set the context. You can just
allow it in your policy. Should have been present even in RHEL5, I think.
