+Subject: [PATCH] admin: Ensure correct ownership when moving to file:// uri
+
+User and group is not restored properly when moving (or copying with
+G_FILE_COPY_ALL_METADATA) from admin:// to file://, because it is handled
+by GIO fallback code, which doesn't run with root permissions. Let's
+handle this case with pull method to ensure correct ownership.
