Nah, he's right. Something weird happened. All the SELinux applets are enabled, and still built without issue, but none of them work as expected:

:/ # busybox sestatus

sestatus: libselinux returns unknown state: No such file or directory
1|:/ # busybox getenforce
Disabled
:/ # busybox ls -alZ /data
