+Subject: nsswitch: handle missing actions properly
+
+Some internal functions need to know if a database has a nonzero
+list of actions; success getting the database does not guarantee
+that.  Add checks for such as needed.
+
+Skip the ":" in each nsswitch.conf line so as not to add a dummy
+action libnss_:.so
