-// Returns whether the auto-enrollment check is required. When
-// kCheckEnrollmentKey VPD entry is present, it is explicitly stating whether
-// the forced re-enrollment is required or not. Otherwise, for backward
-// compatibility with devices upgrading from an older version of Chrome OS, the
-// kActivateDateKey VPD entry is queried. If it's missing, FRE is not required.
-// This enables factories to start full guest sessions for testing, see
-// http://crbug.com/397354 for more context. The requirement for the machine
-// serial number to be present is a sanity-check to ensure that the VPD has
-// actually been read successfully. If VPD read failed, the FRE check is
-// required.
