I see. The error is likely due lack of securityfs in kernel, I used to
have that in the past as I don't have such requirement and just masked
the service (disable is not enough):

 ln -s /dev/null   /etc/systemd/system/sys-kernel-security.automount

That is weird. Maybe you were working with RO filesystem? Or some
tmpfs overlay on top of it?

try to manually execute /lib/systemd/systemd-kmsg-syslogd binary
manually from a working systemd and check what's happening. It never
failed to me.  I don't have the code now (different system) so I can
look what's status=218.
