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.
