Still have shm and devicemapper mounts on directlvm

I recently installed docker 1.12.6 on fedora 25 workstation. More or less from the start I set this up with direct-lvm according to the info on
However, when running a container, I still get shm and devicemapper folder with rootfs mounted.
It’s not a json logging issue because I use the standard journald-logger driver.

Haven’t used the docker-storage service.

I’ve been reading docs and googling but apart from another post here on the forum where the issue was logs in json format I haven’t found anything.

Normally, with the devicemapper directlvm setup I shouldn’t see any shm or other docker mountpoints at all, right? I know /var/lib/docker still holds the named volume if the graphics aren’t changed.

thanks for any light on this issue, I hope it’s just misunderstanding from my part.
