Hmm...that's interesting. umount should run in the same domain as
mount, and they should thus have a type transition on etc_t:file to
etc_runtime_t. ls -Z /bin/umount
Looks like there is no transition defined into mount_t from
unconfined_t? So umount and mount are just run in unconfined_t? And
unconfined_t lacks the type transition?
