LINKBACK syntax

LINKBACK $<$file$\vert$dir$>$ [*] $<$CLASS$\vert$NODE$\vert$target$>$ [-h]
|||||| [-c class[,class]...] [-n node[,node]...]

converts a file or directory in the root filesystem to point to its corresponding location in /ram. At boot time, the location in /ram then points back to a location in the master image based on the node's class or hostname.
| A * star forces the linkback to the specified target even if the target doesn't exist.
| The CLASS target causes the linkback to point to the file or directory having an extension that matches the node's class name.
| The NODE target causes the linkback to point to the file or directory having an extension that matches the node's hostname.
| Any arbitrary file or directory can be specified as the direct target of a linkback. This target is interpolated to replace any instance of `$CLASS' with the node's class name, and any instance of `$NODE' with the node's hostname.
| The -h option specifies that the linkback target should be 'hidden'. Note: Only CLASS and NODE linkbacks use the -h option.
| Supplying any -c options limits the directive to apply only to the given classes.
| Supplying any -n options limits the directive to apply only to the given nodes.
