erofs: Incorrect selinux labels #164
Description
The generated EROFS image does not have correct SELinux labels for certain directories and files. These directories/files end up getting the default_t label.
One example, among many, is /home which is a symlink to /var/home
Here are the labels on the mounted EROFS image
