Maybe it is the blogd from blog package :) it is a dropin replacement for plymouth but without graphical splash screen and with working serial console support.

Curious, I do have it installed. News to me.
What runs it?
This package has two parts blog-plymouth to replace plymouth, that is provide all services even for dracut initrd, and blog which provides the daemon started within initrd. This daemon can switch root to survive switch from initrd to new root (done with the help of blog-switch-root.service). After /var/log becomes writable blogd move the old /var/log/boot.log to /var/log/boot.old and writes out the new /var/log/boot.log. After boot has finished the blogd gets stopped ... btw. on shutdown it will be finally restarted and then blogd appendes as long as possible to /var/log/boot.log. Werner
But the boot log comes from service klog.
This servive does move /var/log/boot.msg to /var/log/boot.omsg and then writes out /var/log/boot.msg as oneshot at boot. Only kernel messages can be found. Beside this console log level and log console is set.
I noticed "/etc/systemd/system/bootmsg.service" (a symlink to /usr/lib/systemd/system/klog.service), from package syslog-service-2.0-lp152.4.7.noarch: # /lib/systemd/system/klog.service # # This file is part of package systemd. # # Copyright (c) 2011 SuSE LINUX Products GmbH, Germany. # Author: Werner Fink # Please send feedback to http://www.suse.de/feedback # # Description: # # Create the well known /var/log/boot.msg # By using dmesg(1) the normal kernel and boot messages handled # by systemd will not disappear.

So there are several components that may write the "boot log" file. - -- Cheers, Carlos E. R.
