 Features:
 
+* port remaining getmntent() users over to libmount. There are subtle
+  differences in the parsers (see #25371 for example), and it hence makes sense
+  if we stick to one set of parsers on this, not mix both.
+
 * run0 and run0 --user=root have different effect on tty ownership?
 
 * get rid of compat with libidn.so.11 (retain only for libidn.so.12)
