本文探讨了Red Hat Enterprise Linux 8.0 (Ootpa)中DefaultTasksMax参数的配置与实际显示值的差异，该参数用于限制单位任务的最大数量，文中展示了通过systemctl与man命令获取的不同结果。

[root@rhel8server1 ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux release 8.0 (Ootpa)
[root@rhel8server1 ~]# 
[root@rhel8server1 ~]#  systemctl show --property DefaultTasksMax 
DefaultTasksMax=11365
[root@rhel8server1 ~]# man 5 systemd-system.conf

       DefaultTasksMax=
           Configure the default value for the per-unit TasksMax= setting. 
		   See systemd.resource-control(5) for details. 
		   This setting applies to all unit types that support resource control settings, with the exception of slice units. 
		   Defaults to 80%, which equals 26214 with the kernel's defaults on the host, but might be smaller in OS containers.

man的结果（ Defaults to 80%, which equals 26214 with the kernel's defaults on the host, but might be smaller in OS containers.）与 systemctl show --property DefaultTasksMax 的结果不一样，暂时不知道为啥？
