FC6 x86_64 - Installer loaded lots of "duplicate" packages?
|

| My newly installed FC6 x86_64 system seems to have lots
of duplicate packages, where the installer loaded both
the i386 and x86_64 versions.
I first noticed this when running yum to load updates.
For example, from yum.log:
> Dec 20 09:43:18 Updated: dbus.x86_64 1.0.1-8.fc6
> Dec 20 09:43:20 Updated: dbus.i386 1.0.1-8.fc6
> Dec 20 09:43:35 Updated: dbus-devel.x86_64 1.0.1-8.fc6
> Dec 20 09:43:36 Updated: dbus-devel.i386 1.0.1-8.fc6
> Dec 20 09:43:37 Updated: dbus-x11.x86_64 1.0.1-8.fc6
The following pipeline finds all packages installed with
more than one architecture:
rpm -qa --queryformat '%-20{ARCH} %{NAME}\n'|sort -k2|uniq -D -s20
This outputs 578 lines, indicating that 289 packages are
installed in both architectures. Here's a sample of the
output:
> i386 alsa-lib
> x86_64 alsa-lib
> x86_64 apr
> i386 apr
> i386 apr-util
> x86_64 apr-util
> x86_64 aspell
> i386 aspell
> x86_64 atk
> i386 atk
> i386 at-spi
> x86_64 at-spi
> x86_64 audiofile
> i386 audiofile
> i386 audit-libs
> x86_64 audit-libs
> x86_64 avahi
> i386 avahi
> i386 avahi-glib
> x86_64 avahi-glib
> x86_64 beecrypt
> i386 beecrypt
[snip]
> x86_64 mkinitrd
> i386 mkinitrd
> x86_64 mysql
> i386 mysql
> i386 mysql-devel
> x86_64 mysql-devel
Is this normal?
Doing "rpm -ql" indicates that the 64-bit version contains
all the files in the 32-bit rpm, so why is it necessary to
have both?
How does RPM manage this so you end up with the right libraries
installed?

Yes this is normal, but to be fair and honest many of the 32-bit packages
are not really needed. Some are required for compatibility reasons with
other third party packages (the 32-bit mplayer and AdobeReader packages
come to mind). The 32-bit libs are needed for the 32-bit applications just
like the 64-bit libs are needed for the 64-bit applications, neither can
work without the proper (32 or 64 bit) libs installed.

This is correct.
X86-64 linux can run both 32 and 64 bit applications.
But in order to run 32 bit programs, they require the 32 bit libraries.
(hence the duplication)

64 bit libraries end up in the lib64 directories, while the standard 32 bit
ones end up in the /lib directories. (so they don't clash)
