Comment:

 Replying to [comment:1 wmb at firmworks.com]:
 > Possibility 4) Fix mkfs-jffs2 to support hard links and amend the
 pilgrim build process to do the shallow copy at build time.  This solves
 the problem to the same degree as (3), and can be automated, but requires
 a fair amount of coding and extensive testing of the new tools.  We should
 probably do it eventually.

 The coding in the tools is fairly trivial.

 Of course, it wants switching from a linked list to a sensible data
 structure such as a tree -- but that isn't hard either. Left as an
 exercise for the reader.
