Note that the class was "filesystem", not "file". So this is a
denial
upon an attempt to mount a filesystem with a context= or fscontext=
mount option. The fact that it was originally unlabeled_t means that
the policy had no entry for the filesystem type in its fs_use or
genfs_contexts configuration. You should have gotten another message
from SELinux (with a SELinux: prefix) when it was first mounted about it
not being configured for labeling.
