+    man: simplify vmautoactivation(7)
+    
+    Previously this was hard-coded to: "Autoactivation commands use a number
+    of temp files in /run/lvm (with the expectation that /run is cleared
+    between boots.)"
+    
+    Since c1bfc8737f08bf7558b2d788e9756f895cd9eaaa it was made more generic,
+    but on some systems this logic leads to "Autoactivation commands use a
+    number of temp files in /run/lvm (with the expectation that /var/run
+    is cleared between boots)." which I'd say adds more confusion than it
+    solves.
