Hi,

I've just ordered a new workstation, with a Core 2 Quad CPU. I want to
run OpenSUSE with a 64-bit kernel and 32-bit userland on it. I have
not had a 64-bit CPU desktop with OpenSUSE yet, so I'm asking for
advice -- what's the best way to do it? (My Google foo was not good
enough to get good answers. :-( )

AFAIU, 64-bit OpenSUSE comes with 32-bit userland programs. Do I get
all programs this way, or only a selection?

Or, do I install 32-bit OpenSUSE and replace the kernel with a 64-bit
one from the build service / factory / vanilla kernel? (I have no
problems compiling my own kernel -- I started using Linux with 0.99.4,
back in 1995...)

In case you're wondering why I want that constellation: I prefer 32bit
userland for its stability and availability of media stuff (e.g.,
win32 codecs), but I also want to run 64bit OSes in VMware instances.
For that I need a 64bit kernel. In addition, it will handle my 8 GB
main memory better than a PAE kernel.

Oh yes, the release of choice will be eventually 11.1; in case that
matters.

Thanks in advance for any recommendation,

Joachim


A user won't notice much difference between 32 & 64 bit apps. Other
than Seamonkey & Firefox, everything on my computer is 64 bit, AFAIK.
Seamonkey & Firefox are 32 bit, due to plugin availability, but 64 bit
versions are available. When you use Yast to install an application,
you can chose 32 or 64 bit versions. 64 bit vi really rocks! ;-)
