Yes, this was yet another difficulty that arose with the change to
systemd from rhel6 to rhel7.  The intent was to solve it first in fedora
when it switched to systemd to address this since the number of startup
messages jumped from manageable within the default backlog size to
almost double.  There are also other improvements upstream that remove
some of the doubt about exactly how many log messages were lost.

It is all there in fedora and RHEL8, so that is one possible route.  It
is a bit late in the RHEL7 life cycle to commit to it, but not
impossible...
