+    drbd: sort file list
+    
+    because it influences the ordering of entries in compat.h
+    which influences srcversion= checksum
+    which prevents drbd.ko from building reproducibly.
+    
+    See https://reproducible-builds.org/ for why this matters.

+    and to not record build user and hostname if requested
