You must be thinking of some flavor of symbolic links other than the one
used in the UNIX systems with which I'm familiar.  In the latter, the
name lookup code finds an inode number, but the inode points to a file
of type "symbolic link", which means the contents of the file are an
alternate path name.  This means the system has to "read" that file and
*then* continue the lookup process.

Assuming, of course, that the symbolic link's contents are an absolute
path name.
