Just an update on the current status about this topic: we've decided to
go ahead and change the henrietta-cache cache format (with regard to the
removal of the "tags" directory), although we know it is not exactly the
rightest thing to do.

The good news is that most things that could break have been covered.

Peter implemented the changes in henrietta-cache and adapted
make-egg-index and make-egg-rss-feed to use the new cache format.  We
now have egg indexes and feeds for CHICKEN 4 and 5:

I've made an egg
( which provides
a drop-in replacement for setup-download's gather-egg-information, with
the bonus of supporting both henrietta-cache cache formats.

I've updated egg-tarballs (the thing that generates to support both cache formats
(support available in version 0.5.0).  We now have egg tarballs for both
CHICKEN 4 and 5.

Peter has set up to serve CHICKEN 5 eggs and Alaric has done
the same for kitten-techs.  We can now install remote eggs with
CHICKEN 5's chicken-install.

chicken-doc-admin, which uses gather-egg-information from setup-download
has not been updated so far.  It can only be used with caches generated
by henrietta-cache < 1.0.0.

salmonella has not been updated yet either.  The use of
gather-egg-information in salmonella is not very critical, since it is
only used in the "local" mode (i.e., chicken-install uses local egg
sources).  None of the test machines use the local mode.  Anyway, I'll
soon add support for both cache formats (probably by using
gather-egg-information, the egg).

I intend to set up some salmonella instances to test the chicken-5
branch soon.

Best wishes.
