LINKBACK syntax
LINKBACK
file
dir
[*]
CLASS
NODE
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.
