I think we should communicate a bit better and refrain from opening bugs as 
soon as something goes wrong, as this is probably the fourth time we file a 
bug for "rustc can't bootstrap itself" and upstream will soon start hating us 
:)

This currently means that our packaging efforts are going backward.
I mean, I already spent time documenting in README.source why (in general) 
bootstrapping from the same version doesn't work, but *may* once rust1 is 
stable. In order to overcome this, we were using a multi-tarball orig.tar.gz 
embedding a stage0 and explaining why.

If you write in the doc...
'This produces the full rust compiler built using your now obsolete
"dlstage0" rustc compiler.'
...I assume you tried and it works now. Which reflects directly into what we 
use as orig.tar.gz, which also means we rewrite doc in order to explain ftp-
masters what we do.

I think this wasn't really clear or agreed upon (at least speaking for 
myself). You are basically trading off the embedded stage0 with the ability to 
build "beta" release channel on Debian infrastructure.

Ciao, Luca
