-Subject: [PATCH] selinux: allow reading labels before policy is loaded
-
-This patch does for `getxattr` what commit 3e3e24b42043 ("selinux: allow
-labeling before policy is loaded") did for `setxattr`; it allows
-querying the current SELinux label on disk before the policy is loaded.
-
-One of the motivations described in that commit message also drives this
-patch: for Fedora CoreOS (and eventually RHEL CoreOS), we want to be
-able to move the root filesystem for example, from xfs to ext4 on RAID,
-on first boot, at initrd time.[1]
-
-Because such an operation works at the filesystem level, we need to be
-able to read the SELinux labels first from the original root, and apply
-them to the files of the new root. The previous commit enabled the
-second part of this process; this commit enables the first part.
