Re: sparc64 and sparc architecture -- any consensus?
Reviving an old thread as I update the sparc64 port pages...

I don't think that 32-bit sparc is really going to disappear for 7
years, at least not in the Linux world. Maybe in the corporate world
it will...

Ideally, we can treat sparc64 as an "overlay".
I think this can be done now in apt. Just install the 64-bit apps in
the sparc64 area, and have people define it first in sources.list:
deb http://http.us.debian.org/debian stable/sparc64 main contrib non-free
deb http://http.us.debian.org/debian stable/sparc main contrib non-free
Even if version numbers are the same, apt should favor the first line.
I'm not sure if this is as robust as it should be, though. For
instance, if we decide to add a critical library into the sparc64
area, it wouldn't get immediately picked up unless we used NMU
numbering for the sparc64 part.
*sigh*....
