我无法在 AlmaLinux 8.7 的全新映像安装上启用 SELinux。
重启后：
[root@cs46949 stdusr]# cat /etc/redhat-release &&
> uptime &&
> dnf -y install policycoreutils selinux-policy selinux-policy-targeted libselinux-utils setroubleshoot-server setools setools-console &&
> dnf update &&
> cat /etc/selinux/config &&
> sestatus

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
SELinux status: disabled
备注：这是同一个问题SELINUX 不会启用，但那个已经关闭并且偏离主题（因为用户在 linode 上使用 linode 提供的（自定义）内核，但不支持 SELinux）。 AlmaLinux 具有 RHEL 二进制兼容内核版本。 4.18.0
答案1
该AlmaLinux 实例由dogado.de 提供，并作为Paralles Virtuozzo 下的虚拟机运行。根据他们的文档，它不支持 SELinux。
