+Subject: [PATCH] stages/files: relabel /var/home and /var/roothome
+
+The behaviour of how `restorecon` handles symlinks changed between RHCOS
+and FCOS. More specifically, `restorecon` will follow symlinks that are
+part of a given path, but not if the target path is a symlink itself.
+On OSTree-based systems, `/home` and `/root` are just symlinks, so the
+newer `restorecon` wasn't actually relabeling anything under there.
+
+Add the real paths to the list of dirs to relabel and add `-i` so that
+it's not a fatal error on non-OSTree-based systems.
