deny mount does not work correctly

Bug Description

Given the following profile,

profile lxc_container flags=(attach_disconnected) {
umount,

# ignore DENIED message on / remount
# FIXME: doesn't match yet
deny mount options=(ro, remount) -> /,

# allow tmpfs mounts everywhere
mount fstype=tmpfs,

# allow bind mount of /lib/init/fstab for lxcguest
mount options=(rw, bind) /lib/init/fstab.lxc/ -> /lib/init/fstab/,

# deny writes in /proc/sys/fs but allow fusectl to be mounted
mount fstype=binfmt_misc -> /proc/sys/fs/binfmt_misc/,

# deny writes in /sys except for /sys/fs/cgroup, also allow
# fusectl, securityfs and debugfs to be mounted there (read-only)
mount fstype=fusectl -> /sys/fs/fuse/connections/,
mount fstype=securityfs -> /sys/kernel/security/,
mount fstype=debugfs -> /sys/kernel/debug/,
}

the rule

deny mount options=(ro, remount) -> /,

does not work correctly
