Slight correction - he actually renamed it to build-debian-cloud, not debian-build-cloud, despite the email typo.

I agree any shift from build-debian-cloud to Debian-Installer, if Debian decides that's desired, would be over the longer term. With my Googler hat on, the important goal is a reproducible method that gives an image Debian and Google feel comfortable supporting and which works for the ways cloud customers use images. With my Debian developer hat on, I hope that any system which pays sufficient heed to Appendix D.3. of the Installation Manual will be sufficiently standard Debian to be supportable, and any deficiencies there should be fixed in the manual as well as in implementations of that appendix. - Jimmy
