RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Version-Release number of selected component (if applicable):
systemd-219-57.el7_5.1.x86_64
Comment 2 Orion Poplawski 2018-12-31 20:42:42 UTC 
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.
Comment 8 Jan Synacek 2019-03-18 08:43:26 UTC 
I can't reproduce this. Did you perhaps remove the configfs directory manually?
Comment 11 Orion Poplawski 2019-03-18 16:42:13 UTC 
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
