Hi,

I've just been checking my local copy of the CentOS repos. I found 200+ i386/i686 packages in both the updates/5/RPMS and updates/6/Packages directories.

I checked with my rsync site ( ftp.heanet.ie ) and the equivalent UK site ( ftp.mirrorservice.org ) and they both carried these packages also.

Is this a case a repo pollution, it can't be necessary to have i386 packages in the x86_64 updates. Just checking before I delete these packages.

no it's probably not repo pollution. try to google for multilib

for example: http://blog.nexcess.net/2012/07/19/64-bit-centos-installing-32-bit-packages/

Thanks Nicolas, John.

These repos are for a bunch of 64 servers, the only one of which requires 32bit packages is the one that runs Oracle ;-)

I might as well leave them there, disk space is cheap.

Thanks again.

You need them to run i386 apps on a x86_64.

True, but i386/i686 packages are usually still only located in the 32bit repo directories...they're not usually intermingled in the actual download directories, last I checked.

It has been being done this way since x86_64 was first released by Red Hat ... See Fedora Core 1's x86_64 updates directory and search for i386. http://archives.fedoraproject.org/pub/archive/fedora/linux/core/updates/1/x8...

They still do it that way in their latest release: http://dl.fedoraproject.org/pub/fedora/linux/updates/17/x86_64/

We have been doing it that way since our first release as well: http://vault.centos.org/3.1/updates/x86_64/RPMS/

It is just how multilib is done in Red Hat type distributions.

My apologies...I stand corrected.
