journald setting RuntimeMaxFileSize seems to be ineffective
by berndbausch from LinuxQuestions.org on (#4ZGMN)
I am trying this on Centos 8. From the journald.conf man page:

However, RuntimeMaxFileSize seems to be ignored. I specify 4M, the file is 8M. Yes, I restarted the service and even rebooted.
Code:# grep RuntimeMax /etc/systemd/journald.conf
#RuntimeMaxUse=
RuntimeMaxFileSize=4M
#RuntimeMaxFiles=100
# journalctl -u systemd-journald --no-pager
