|     _stackmanager: set some variables to prevent coverity warning
|     
|     Comes in via an eval() of ipsec addconn --configsetup

+# Tehse prevent coverity warnings, variables come in via ipsec addconn call
+xfrmlifetime=""
+overridemtu=""
+fragicmp=""
+hidetos=""

How can this work when the addconn invocation setting the variables to
the correct value seems to come before this set of assignments?

(Note I know nothing about this code so I may have this all wrong.)
