Comment 7 for bug 1489379

------- Comment From <email address hidden> 2015-09-03 11:56 EDT-------
Okay, using a custom libchecktur.so built without -fexceptions..
It works fine in the installer environment, for its purposes.

This should be OK as there's no multipathd (which exercises the path checkers more) running in the installer.
I'll formalize/support this in another comment.
