This may come as a shock to many people on the list ... but by default
on CentOS-5.x (and also CentOS-4.x or 3.x), when you do an x86_64
install it also installs many i[3,6]86 packages. This is not the
default behavior in CentOS-6.x (it installs only x86_64 by default).
This is the default behavior in RHEL and so it is also the default
behavior in CentOS.
Anaconda and yum both install these i[3,6]86 packages and update them by
default for c5 and earlier.
If you wanted to have only 64-bit packages installed, then you would
just add this line to your .rpmmacros file to be able to see which
packages are i[3,6]86 and which are x86_64:
%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}
Before you add that, you will get this:
==================
rpm -q glibc
glibc-2.5-65.el5_7.1
glibc-2.5-65.el5_7.1
=================
Afterwards:
rpm -q glibc
glibc-2.5-65.el5_7.1.i686
glibc-2.5-65.el5_7.1.x86_64
=================
Now you can remove all the i[3,6]86 packages if you want ...
=================
Specifically for perl ... at one time, RHEL had perl.i386 in their
x86_64 tree and it was removed ... we did the same thing in CentOS (if
you look at the 5.7 tree, there is no i386 perl).
If you installed at an earlier time and upgraded, it is possible that
you have an i386 perl (CentOS-5.1 had it there, it was taken out in
5.2). Is it possible that these machines were 5.1 installs and updated?
So, you have 2 choices ... you can try to remove the perl with this command:
rpm -e perl.i386
If you have nothing that specifically requires that arch of perl, that
will remove it.
OR
We did add the i386 version of perl to the x86_64 c5 extras before for
this same reason before ... and I see no negative to doing it again with
the latest version of perl.i386 ... but unless you really need it, I
would recommend removing it.
I am adding the i386 version of perl to x86_64 extras for c5 now ... it
will go out to the mirrors soon.
