Dear Sir,
Recently, I downloaded a 32bit version of Debian from the following
website:

http://cdimage.debian.org/debian-cd/6.0.1a/i386/iso-dvd/

However, after finishing installation, I found that the 32bit OS
turned out to be amd-64bit:
uname -a
Linux my-computer 2.6.32-5-amd64 #1 SMP Tue Mar 8 22:49:26 UTC 2011
x86_64 GNU/Linux

I wonder if there is anything wrong? Thanks very much for your
attention.

Best,

Can you post:

$ dpkg -l|grep linux-image

in your system.

Did you have a 64-bit kernel installed on a 32-bit host.

'dpkg-architecture -qDEB_HOST_ARCH' will show which architecture the
rest of the system uses.

A 64-bit kernel is not supposed to be automatically selected, but it
could be if the system has 4 GB RAM and the '686-bigmem' flavour is not
available for some reason.

Please use 'reportbug installation-report' to provide more information.
The debian-devel list is not the place to send bug reports.

dpkg --print-architecture is better suited (dpkg-architecture is a
dpkg-dev script).

dpkg --print-architecture shows
i386.

However, uname -a shows
x86-64

what does this mean?

Best,

It means Asias He was right. And this is a perfectly valid
configuration (though it confuses some third-party installers).

But I think this is a bug in the configuration of the CD/DVD creation:
the amd64 flavour is on DVD 1 but the 686-bigmem flavour is on DVD 2.
The latter definitely should be on DVD 1 (and CD 1 or 2, rather than CD
10!).

How is that a problem? An overwhelming majority of CPUs today are amd64,
and even if you choose to install a i386 userland (there are various
good reasons for that), you still want an amd64 kernel to benefit of all
your CPU can offer.

There are compatibility issues with third-party scripts that rely on
'uname -m' to select which architecture to use in userland. And there
are still a few places where 32-bit compatibility wrappers are missing
in the kernel. Personally, I do use this combination, but I'm not ready
to recommend it in general.

Is there a compelling reason for init not to set the right personality?
