Трассировка стека команды монтирования показывает ошибку `` Файл не найден ''

Когда я запускаю программу, я получаю сообщение об ошибке монтирования:

[root@host ~]# ip vrf exec wan1 /usr/sbin/ssh root@1.2.3.4
Failed to mount cgroup2: No such file or directory

Я знаю, что мое ядро ​​поддерживает cgroup2:

[root@host network-scripts]# cat /proc/filesystems 
nodev   sysfs
nodev   rootfs
nodev   ramfs
nodev   bdev
nodev   proc
nodev   cpuset
nodev   cgroup
nodev   cgroup2
nodev   tmpfs
nodev   devtmpfs
nodev   configfs
nodev   debugfs
nodev   tracefs
nodev   securityfs
nodev   sockfs
nodev   dax
nodev   bpf
nodev   pipefs
nodev   hugetlbfs
nodev   devpts
nodev   autofs
nodev   pstore
nodev   efivarfs
nodev   mqueue
nodev   selinuxfs
        xfs
        vfat

Вот след вышедшего из строя крепления:

[root@host tmp]# strace -e trace=mount ip vrf exec wan1 /usr/sbin/ssh root@1.2.3.4
mount("none", "/var/run/cgroup2", "cgroup2", 0, NULL) = -1 ENOENT (No such file or directory)
Failed to mount cgroup2: No such file or directory
+++ exited with 1 +++
[root@host tmp]# 

У меня есть пустой каталог:

[root@host tmp]# ls -la /var/run/cgroup2
total 0
drwxr-xr-x.  2 root root  40 Jul 31 12:53 .
drwxr-xr-x. 27 root root 800 Jul 31 13:25 ..
[root@host tmp]# 

Есть идеи, почему я получаю эту ошибку? Я работаю на Centos 7 с ядром 4.17.10-1

Спасибо за любую помощь
