Version-Release number of selected component (if applicable): systemd-219-57.el7_5.1.x86_64
Still present with systemd-219-62.el7.x86_64 on certain systems. Some perhaps notable differences between "systemctl show sys-kernel-config.mount" on EL7 and Fedora 28: EL7: MountFlags=0 Requires=-.mount Wants=system.slice Conflicts=umount.target Before=local-fs.target sysinit.target After=systemd-journald.socket system.slice -.mount systemd-modules-load.service Fedora 28: ForceUnmount=no MountFlags= Requires=-.mount system.slice Before=sysinit.target After=systemd-modules-load.service -.mount system.slice systemd-journald.socket Perpetual=no CollectMode=inactive though there is no real difference between /lib/systemd/system/sys-kernel-config.mount on the systems.
I can't reproduce this. Did you perhaps remove the configfs directory manually?
Haven't touched configfs as far as I know: # mount | grep config configfs on /sys/kernel/config type configfs (rw,relatime) # ls /sys/kernel/config rdma_cm/
