Does it work correctly as a root file system?

The following extract from reiserfsck(8) indicates that it won't:

       --rebuild-tree
              This option rebuilds the entire filesystem tree using leaf nodes
              found  on the device.  Normally you only need this option if the
              reiserfsck  --check  reports  "Running  with  --rebuild-tree  is
              required".  You are strongly encouraged to make a backup copy of
              the whole partition before attempting the --rebuild-tree option.
              Once  reiserfsck  --rebuild-tree  is  started it must finish its
              work (and you should not interrupt it), otherwise the filesystem
              will  be  left in the unmountable state to avoid subsequent data
              corruptions.

Unless of course they want to do some common file system recovery options such 
as putting an image of a file system on another file system.  The last 
reports were that if you put a Reiser3 image as a regular file in a Reiser3 
file system then fsck would really mess things up.

How is it lacking?  In a quick test it seems to work.
