Huh. When I run it I got
[root@localhost ~]# last

reboot system boot 4.18.0-80.11.2.e Fri Oct 18 09:39 still running

In el7 it used to be in this package:
[smooge@batcave01 ansible (master)]$ rpm -qf /usr/bin/last
sysvinit-tools-2.88-14.dsf.el7.x86_64
And in el8 it is in
[root@localhost ~]# rpm -qf /usr/bin/last
util-linux-2.32.1-8.el8.x86_64
The wtmp file is owned by
[root@localhost ~]# rpm -qf /var/log/wtmp
systemd-239-13.el8_0.5.x86_64
However as you can tell from above this system has been installed for
a bit so I am guessing whatever creates wtmp hasn't happened?
