My second question is what are people's opinions about including
all
architecture-specific libraries in a single i386 package vs. separating
them into subpackages. A base set of atlas libraries is a 5 MB package
(and bigger installed of course), part of the reason I think that the
Debian packages for atlas are all separated into subpackages (atlas-sse,
etc).
I would go for 1 big package. Reason: it's really unfunny to otherwise
make sure the right package gets installed automatically (other than
installing the lot anyway, at which point you might as well make one big
one)
