Bug#683424: Patch describing Multiarch
tag 683424 patch
thanks
Hi,
> We need some introduction to multi-arch.
Attached patch adds a basic introduction to Multiarch in the What's new
section, referring to the HOWTO for extended information for those who
want it. Besides it points users of ia32-libs, probably one of the most
significant use cases, to the steps they need to take to ensure a smooth
upgrade.
Perhaps more could be improved, but this patch should at least satisfy a
large number of common cases. Please apply.
Cheers,
Thijs

+New in &release; is <em>multiarch</em>. Multiarch lets you install packages from
+multiple architectures on the same machine. This is useful in various ways,
+but the most common is installing both 64 and 32-bit software on the same
+machine and having dependencies correctly resolved automatically. The
+&debian; wiki has
+<ulink url="http://wiki.debian.org/Multiarch/HOWTO";>an extensive manual</ulink>
+on how to make use of this functionality if you need it.

+The <systemitem role="package">ia32-libs</systemitem> package is now a

+If you have <systemitem role="package">ia32-libs</systemitem>
+installed, see the upgrade instructions in the amd64 release notes
+on special steps to take.
