Oh yes!
You cannot imagine all the cleanings that (we they are doing behind your
back :)
A bootstrap is really a kick in the ass to produce a much much better
system.
Thanks you guys for making my dream becoming true.

Hi all,
In case you do not know, we work on bootstrapping Pharo, i.e.
create a Pharo image from sources, not based on a previous image
(well, we use a pharo image to produce it but no code / state from
it).
This process will allow to define a minimal Pharo kernel
(currently 52 packages but we could have it far smaller) and to
modularize the whole image (currently packages have too much
dependencies on packages already loaded into the image).
The bootstrap process also allows to write down the recipe to
initialize a new image from scratch (some code is missing in the
image or is wrong). In addition, I think we will clean a lot of
historical objects that are not used anymore.
With the amazing work done by Guillermo Polito during his Phd
(around Espell, Oz):
https://guillep.github.io/files/publications/Poli15Thesis.pdf, *we
succeeded to get a first prototype of a bootstraped Pharo 5 image
(from 5.392)*.
This prototype is able to run an eval command line handler and to
log output / errors. Not all classes are yet initialized and you
cannot yet save / restart this image but it is a big step forward.
It is a 4 mb image (could be half the size without unicode data).
You can download it at:
http://chercheurs.lille.inria.fr/~demarey/pmwiki/pub/pharo-bootstrap/pharo-bootstrap.zip
<http://chercheurs.lille.inria.fr/%7Edemarey/pmwiki/pub/pharo-bootstrap/pharo-bootstrap.zip>.
Next steps are to have a bootstrapped image fully working, then to
load packages on top of it (like network, sunit) to produce a
minimal image.
Then, we need to implement an Oz VM on top of Spur.
After that, we need to work on a reliable way to build the
bootstrap (not too sensitive to changes in the image).
Christophe.
