So, of the three options:

1. do nothing currently and get the pac each time
   a. wait for the ctrl interface
   b. wait for DBus interface

2. create a temp file (/var/run/NeworkManager/eap-fast-pac) to read/write the
   pac file from.

As 2 is only a stop-gap, I guess I should just wait for 1.a/1.b.
