CentOS - Dec 2019 - systemctl behaves like it is being piped to less in centos 8?

Comparing the output of systemctl between centos 7 and 8:

[root at mail ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root at mail ~]# systemctl status firewalld
? firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled;
vendor preset: enabled)
   Active: active (running) since Fri 2019-10-25 00:24:24 UTC; 1
months 19 days ago
     Docs: man:firewalld(1)
 Main PID: 6578 (firewalld)
   CGroup: /system.slice/firewalld.service
           ??6578 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid

Warning: Journal has been rotated since unit was started. Log output
is incomplete or unavailable.
[root at mail ~]#

So far so good. Don't know why it is complaining about log being
rotated but output looks readable. Now, let's grab a centos8 box:

[raub at vmhost2 ~]$ cat /etc/redhat-release
CentOS Linux release 8.0.1905 (Core)
[raub at vmhost2 ~]$ systemctl status firewalld
? firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor
p>
   Active: active (running) since Tue 2019-12-10 20:10:20 EST; 2 days ago
     Docs: man:firewalld(1)
 Main PID: 1031 (firewalld)
    Tasks: 2 (limit: 26213)
   Memory: 33.5M
   CGroup: /system.slice/firewalld.service
           ??1031 /usr/libexec/platform-python -s /usr/sbin/firewalld --nofork
>
lines 1-9/9 (END)

As you can see, it is trimming the output at the end of my terminal
window, which I do not care; there are options (-i I think) to make it
wrap around, but the line

lines 1-9/9 (END)

is what is annoying me. That seems to be what I would expect if I
piped it to less. I checked a fedora 31 and another centos 8 box and
am seeing the same behaviour. Am I missing something?

The environment variable $PAGER determines what pager to use.  The
default is 'less'. User 

  export PAGER=more 

to use 'more' instead. Or

 export PAGER
to not pipe to a pager.

It seems this became the default at some point.

systemctl -l --no-pager

is the way to get it without that. The whole does it use a pager, does
it ellipse, etc has been a long fight where various people complain
enough to get it one way or another. It usually goes with the group
that complains the nicest versus the ones who complain the worst :).

You can fix the symptom with the software as delivered:

     $ export SYSTEMD_LESS='-FR'

See https://bugzilla.redhat.com/show_bug.cgi?id=713567 for info. It's
more of the systemd-mindset disease, and Schmidt looked to be pretty
intransigent in the face of concerted objection some years ago.

You either have to use: systemctl --no-pager status firewalld
Or you have to first do: export SYSTEMD_PAGER
Maybe you could put the latter into a file in /etc/profile.d to make
it system-wide:

# echo 'export SYSTEMD_PAGER=' >>/etc/profile.d/systemd.sh
# echo 'setenv SYSTEMD_PAGER ""'
>>/etc/profile.d/systemd.csh

This would also affect "man". Better to use SYSTEMD_PAGER.
