Getting "operation not supported" messages on a long ls listing with
unionfs mounts. Trying to setup a jail using unionfs, has anyone any
ideas why I'm seeing this with ls?

# mount
/dev/da0s1a on / (ufs, local, noatime, soft-updates, acls)
devfs on /dev (devfs, local, multilabel)
/dev/vinum/usr on /usr (ufs, NFS exported, local, noatime, soft-updates, acls)
/dev/vinum/var on /var (ufs, local, noatime, soft-updates, acls)
<below>:/usr/jail/template on /usr/jail/172.16.1.1 (unionfs, noatime, noclusterw, acls)
^^^^^^^
