 Outstanding TBDs
 ````````````````
+* How do we retrieve ``last-change``?

+Resolved TBDs
+`````````````
 * We support ``arbitrary-names``, right?  Pretty sure GRE / tuntap / etc all
   let you name things whatever you want.
 
+  **Resolution**: No.  We do not, as some Linux network tooling cannot properly
+  handle UTF-8 names.
+
 * Do we support ``pre-provisioning``?  It would make sense, since /e/n/i and
   /e/c/n both let you just specify whatever configuration you want for whatever
   interfaces you want.
 
-* Where do we store interface ``description``?
+  **Resolution**: Yes.

-* None.
+  **Resolution**: /e/n/i can do ``netconf-description`` keyword, /e/c/n (if
+  we support it) can do ``description_$IFACE``.
