This has got me a little worried:-
Somewhere recently, it might have been this list or the CentOS list,
there was a thread asking why not compile everything for the i686
architecture instead of i386 to obtain higher performance?
The answer stated that the performance increase would only be about 1%
therefore hardly worth the trouble. More seriously, in my case, the
answer also stated that compiling for the i686 architecture would
prevent software from working in machines with Eden processors. Which is
exactly what I've got here, running a subversion server.
Here is the output from yum update on this machine:-

Is this ok [y/N]:
In the learned opinion of the list, will it cause me problems if I
answer y?
i.e. will this update with two i686 architecture components cause my
Eden processor server to crash?
If so is it possible for me to get i386 architecture updates only?
Check what you've already got:
$ rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n' glibc kernel
I'm pretty sure you'll find you're already running i686 versions of
these packages.
