+- shim-install: Add ca_string for SL Micro to update fallback loader
+
+  The fallback loader, /boot/efi/EFI/BOOT/bootaa64.efi or bootx64.efi,
+  cannot be upgraded by shim-install on SL Micro. The issue case is
+  SL Micro 6.0. It causes that system gets regression bug because it's
+  fallback to a old shim. So this patch adds ca_string to SL Micro.
+  (bsc#1254336)
