+Optional common fields:
+ links [integer]: Number of hard links to this file, generally only
+ reported if greater than 1.
+ inode [string]: String specifying the inode number of this file when
+ it was dumped. If "links" is greater than 1, then searching for
+ other files that have an identical "inode" value can be used to
+ determine which files should be hard-linked together when
+ restoring. The inode field should be treated as an opaque
+ string and compared for equality as such; an implementation may
+ choose whatever representation is convenient. The format
+ produced by the standard tool is <major>/<minor>/<inode> (where
+ <major> and <minor> specify the device of the containing
+ filesystem and <inode> is the inode number of the file).
