The index for the install table. There are four install
configurations defined in the router, default, preferred,
temporary and current. The router will attempt to use these
in the order temporary, preferred, default when it boots.
An install that is undefined will be skipped, an install
which points to a file which is not present will be skipped.
When the temporary install is used, the information is deleted.
The current configuration shows what the router currently
has installed.
