Re: BZR and the bootstrap

[Angelo Graziosi]

Ok, I have done some experiment.

$ bzr checkout http://bzr.savannah.gnu.org/r/emacs/trunk emacs-trunk

$ bzr checkout --lightweight http://bzr.savannah.gnu.org/r/emacs/trunk 
emacs-light

$ rsync -av --exclude=.* --delete emacs-trunk/ emacs-stripped-01/

$ rsync -av --exclude=.* --delete emacs-light/ emacs-stripped-02/

I get

$ du -s emacs-trunk emacs-trunk-light emacs-stripped-01 emacs-stripped-02

337M    emacs-trunk
113M    emacs-trunk-light
112M    emacs-stripped-01
112M    emacs-stripped-02

So, which is the best tree for bootstrap?

BTW, 'emacs-trunk' has a '.bzr' file of 226 M!

Ciao,
Angelo.
