What kind of entity this package is for. Valid rev files
have type chassis(2), slot(3), or port(4).
invalid(1) indicates this entry is not a valid rev file.
deleted(5) indicates this entry refers to a file that was deleted
and is no longer in the management card storage area. This entry
may be re-enabled if the identical file is again put on the
management card. This way, indexes do not move around if files are
deleted and subsequently restored. However, deleted slots may be
reused by the system for new files at the system's descretion.
Setting deleted(5) will delete this file permanently from the
management card storage area.
No values other than deleted(5) can be set.
